A two-stream air ventilator, the flow of which depends on the relative humidity in the room
It also allows for manual closing, causing only minimal airflow
Air flow at 10 Pa: 5–30 m³/h

Self-regulating air ventilator by means of the pressure difference inside and outside the room
Air flow at 10 Pa: 6–27 m³/ h
Acoustic attenuation: Dn, e, w = 32 dB

Maintenance-free air ventilator, the flow of which is regulated depending on the humidity in the room
Can be used with an anti-smog filter
Airflow at 10 Pa: 8–30 m³/h

The air ventilator is automatically controlled by the pressure difference, with the possibility of closing for minimal air flow
Air flow at 10 Pa: 6–24 m³/ h
Acoustic attenuation: Dn, e, w = 34 dB

The diffuser is controlled by the differential pressure and is distinguished by its narrow design
Air flow at 10 Pa: 15 m³/h
Acoustic attenuation: Dn, e, w = 36 dB

Aluminum diffuser with a flat design
Suitable for mounting above or below a glazing unit with a width of 24, 28, 29, 33 or 34 mm
It can be closed using an additional switch

A rebate vent, which is placed in the inner part of the frame, makes it almost invisible when the window is closed
This allows air to circulate at the point of installation
Air flow (for two diffusers) at 10 Pa: 5 m³/h

To be mounted on the glass or in an independent window field between the crossbars
Air damper with the degree of opening regulated by means of manual levers
It has a thermal insulator in the cross-section and a perforated insect screen

To be mounted on the glass or in an independent window field between the crossbars with an adaptive profile
Air damper with opening adjustable by means of manual levers
It has a thermal insulator in the cross-section and a perforated insect screen

To be mounted on the glass or in an independent window field between the crossbars
Air damper with the degree of opening regulated by means of manual levers
It has a thermal insulator in the cross-section and a perforated insect screen

An aluminum pressure diffuser adapted for installation over a glazing unit with a thickness of 23, 24, 25, 26, 35, 36, 37, 38, 39, 40, 41 i 42 mm
It can be closed using an additional lever
Air flow at 10 Pa: 52 m³/h/m

aluminium pressure-controlled vent
I-flux technology
optional Pollux PM10 filter
can be controlled with a pull cord
air flow at 10 Pa: 16.4 l/s/m

Self-regulating trickle ventilator, where the airflow depends on the relative humidity within the room.
It allows for manual locking of the ventilator in the maximum or minimum airflow position.
Airflow at 10 Pa: 7–28 m³/h.

Self-regulating ventilator operating by means of the pressure difference between the interior and exterior of the room.
Airflow at 10 Pa: 7–29 m³/h.
Acoustic attenuation: Dn,e,w = 44 dB.

Self-regulating pressure-controlled rebate trickle vent (PVC)
Installation requires milling the sash rebate and removing a section of the frame gasket
Possibility of installing up to 3 vents per sash (depending on the sash width)
