Inlet window valves, such as the Air Box Comfort, are essential for preserving the quality of indoor air because they let in fresh air while blocking out noise and pollutants. These valves are crucial for establishing a cozy and healthful home, particularly in contemporary, well-insulated homes where natural ventilation may be restricted. Homeowners can enhance the air quality, energy efficiency, and general comfort of their homes by making educated decisions based on their understanding of the various kinds of inlet window valves that are available.

What are Airboxes??

The purpose of airbox devices is to preserve the natural air aeration that occurs inside windows when the sashes are closed all the way.

Because of movable air dampers, they operate automatically when the window is fully closed.

Modern Air Box valves close themselves in response to increased wind, which lowers the amount of air that enters the space.

By adjusting the amount of humidity in the air, you can lessen the possibility of condensation conditions that lead to biological contamination when the dampers operate automatically.

Principle of operation for the Air Box valve:

1. An AirBox housing is mounted on the sash and window frame; to do this, part of the factory window seal is removed.
2. Through the formed hole in the window system, street air enters the room.
3. The process of regulating the air supply occurs thanks to the adjustment knob of the device, moving it to the right/left position; in some versions it is of a rotary type.
4. Due to the natural pressure difference between the air and the room, approximately 10 Pa, air from the external environment will flow into the internal.
5. The dampers are designed in such a way that colder outside air is directed upward, heated there by warmer air and distributed evenly throughout the room, as a result of which drafts do not enter and the overall air temperature does not drop.

Take note! One typical operating condition for the first series of window supply valves is that they cover themselves in ice at temperatures outside the window of -15 C and lower.

The greatest difference in the draft occurs during the autumn-winter season of the year, as the efficiency of the AirBox is dependent on the pressure difference, which is measured both inside and outside the room.

Cravings are influenced by a variety of external factors in addition to the climate season, such as the location of the window in relation to the cardinal directions, the height of the house, the wind speed, and the local climate.

Experts advise against closing the AirBox supply valve all the way when making adjustments.

What types of windows are they suitable for??

Supply-type airbox valves are suitable for all contemporary window systems, including wood, aluminum, and plastic ones, and offer a wide range of installation choices.

The ventilation valve’s design takes this idea into account. He doesn’t detract from the appearance of the sash or frames made of any material when installed.

The body is not impacted by the simplest Air Box installation scheme that doesn’t require milling; all that is required is the installation of a thinner product and the removal of a portion of the standard window seal on the sash and frame. The supply valve body is installed in the same location but with a new seal.

To the greatest extent possible, the installation of these ventilation devices is required for both private homes with inadequate natural ventilation and buildings made of monolithic reinforced concrete. Due to the fact that these facilities will require you to open the windows and vents more frequently, which increases heat loss and raises the cost of heating the space. Additionally, windows that are open contribute to more street noise.

What types of ventilation systems are there??

There are various variations of supply type airbox valves available, including Standard, Comfort, Comfort S, and Eco with G3 filter. KR, VA, and TF are all compatible with window profiles. The installation options, performance traits, and aesthetics of the series vary from one another. You can also buy a noise-reducing visor for the valve and have it placed over the inlet.

Сomfort

The new generation of Air Box valves is more well-liked by consumers due to its increased efficiency. There are two ways to install comfort valves: either replace the window seal in the Standart series or mill the overlay of the frame to accommodate the valve. Better performance is offered by the latter choice.

Another distinction from the basic model is the placement of a single valve—an air supply regulator in the shape of a flat "tongue"—in the device’s center. It is able to move in a plane that is horizontal. The regulator is positioned in the far right position to ensure maximum air flow. The supply of air happens vertically.

Installing Air Box Comfort on both conventional and swing-out swing frames is possible due to its universality. Three screws and two identical pieces of seal are included with the valve.

The drawback is the additional filter installation, which results in comparatively low productivity by air.

Installation types

There are two methods for installing supply type airbox valves, depending on the product’s production series. The easiest way to avoid milling a PVC profile is to use this one. Standard, Comfort, and Eco models are permitted, and Comfort S, which has more intricate milling, is exempt.

In the first scenario, installation is completed as fast and easily as possible, but the valve’s flow rate is lowered from about 42 to 23 m 3 per hour. The second option, which guarantees maximum ventilated air performance but also modifies the window’s main structure, can only be installed by experts.

Horizontal installations at the top of the sash are the most typical. A ventilation duct with two 1×16 cm holes is drilled or cut into the upper portion of the sash during the milling process.

Additionally, there are two ways to install the visor: externally and hidden. In the first, the window is hidden milled; this is done by milling a portion of the PVC frame overlay from the side of the sealing rubber so that the visor stays inside the frame’s plane. The second version has holes milled through the frame overlay, making it simpler externally.

Crucial! The necessary configuration for the visor and valve installation is established based on the window structure’s frame profile and any extra accessories installed, such as flower beds, grilles, and nets.

Installation tools

The device has been meticulously prepared for installation by the manufacturer.

The contractor can easily prepare the remaining basic tools, which are readily available for nearly all do-it-yourself enthusiasts.

In order to precisely measure the installation location on the frame, you will first need a measuring tool, such as a tape measure or ruler. Next, you’ll need a pencil so you can draw on wood and plastic. Applying marks with a marker or another comparable dye is not advised.

Depending on the installation option, different tools are needed to install Air Box valves on windows. For the manufacturer’s mount included in the kit, you’ll need a screwdriver and a sharp knife if you’re not milling.

You will need a jigsaw and an electric drill with drill bits (10/12 mm, respectively) for the Comfort/Comfort-S series if the installation calls for milling the frame and sash.

Step-by-step installation instructions

Installation for various Air Box valve series is contingent upon the following modification: Air-Box ECO with filter installation; Standard: regular without milling; Comfort S: with milling.

Installing Air Box Standard valves is the easiest option. To accomplish this, the performer needs to take the following actions:

1. Determine the location of the device on the sash.
2. Place the body on the sash and mark the required length on the rubber seal.
3. Cut off the marked piece of sealant.
4. A seal is inserted into the free space, which is supplied by the manufacturer, for example, for the Standart series – 250 mm.
5. Remove the protective film on the case.
6. Place the body on the sash and secure it with self-tapping screws.
7. Close the window and mark the required dimensions on the frame to remove the seal.
8. Cut off the marked piece of seal from the frame.
9. Install the seal, which is included in the ventilation device kit, into the free space.

It should be noted that installation time should not exceed thirty minutes, even for performers who are doing this work for the first time.

Using the milling technique, installation technology for the Comfort S Airbox supply valve:

1. Determine the location for the housing.
2. A 350 mm section of the sealing rubber is cut off on the valve, which corresponds to the size of the valve body and the seal included in the kit.
3. Install a seal in the free space.
4. Place the valve on the sash, close it and mark the location of the frame.
5. On the frame overlay, 2 slot holes are milled, 12 mm in height and 157 mm in length, with a distance between them of 12 mm.
6. Insert the support sleeve and secure it with self-tapping screws.
7. Place the valve in the marked place.

In order to prevent the housing from moving and damaging the installation tape, you must make sure that the mounting seals and mounting "claws" of the housing are firmly pressed against the dowels when installing the valve. Installation with milling is typically completed in two hours or less by specialists.

Possible difficulties and errors

An improperly installed airbox valve may result in low ventilation, icing of the device, and a breach of the room’s temperature regulations.

There are no unique challenges for an installer of any skill level when installing without milling; however, experts should handle the milling of the window’s frame and sash because a poorly installed window may completely fail.

When installing the AIR BOX ventilation system, contractors typically make the following mistakes:

1. Incorrect marking of the housing installation; after installation it rests on a slope. If this cannot be avoided when choosing an installation, it is better to provide a vertical installation option, and the valve should be installed as high as possible.
2. Incorrectly performed drilling, weakening the rigidity of the window structure, which is especially dangerous with a large glazing area.
3. Rough milling of the profile, the tightness of the reinforced chamber is broken with the destruction of the anti-corrosion coating.
4. Incorrect valve model selected, not suitable for specific window profile.
5. Incorrect installation height of the device. The height of the valve is about 9mm; if it turns out that there is not enough space for it on the window, this will cause icing of the case even at low subzero temperatures. In this case, it is better to install the device vertically.

How to close if necessary?

Certain Air Box valve models, such as the most basic and affordable Standart series, are incapable of closing all the way.

To put the device at a level where it can be upgraded with more services, this point needs to be made clear when the device is purchased.

You will need to use masking tape to cover the external ventilation holes if it becomes necessary to close such a valve.

The most recent Air Box valve versions are compatible with auto-closing valves. When a significant wind occurs outside the window and creates an excess draft pressure of more than 10 Pa, a functional general house hood will automatically close the valves to prevent excessive heat loss in the event of severe frost.

Advantages and disadvantages

With their versatile applications and straightforward design principle, Air Box supply ventilation valves are ideal for a variety of contemporary window systems, including those found in public, commercial, and residential spaces.

The following are the benefits of ventilation overhead window systems, according to experts and users:

• universality, the possibility of application for different types of window systems;

Some users list the low ventilation volume for models where this figure is less than 23 m3 /hour and the lack of automatic regulation, especially for the Standart series, as drawbacks of this modification of Air Box valves. They also mention the need for specialists to install the device using the milling method.

Average prices for installation services

The device series, window design, vertical or horizontal installation location, throughput, and the existence of additional devices, like an ECO series filter, all affect how much it costs to install Air Box valves.

It should be noted that average installation costs are calculated using a productivity of 20–35 cubic meters per hour at a pressure drop of 10 Pa.

The average cost to install Air-Box valves is:

• Standard without visor and without perforation — 450 rub.;
• Comfort without visor and perforation — 700 rub.;
• Comfort with visor and without perforation — 1000 rub.
• Comfort-S without visor with perforation — 1400 rub.
