The requirements set by the Swedish National Testing and Research Institute of the least degree of separation for the various filter classes are set out in the table below.
The average degree of separation must exceed the minimum degree of separation at 0.4 amp; 0.85 µm. Our test values are shown as a comparison in the table.
How to order:
Filter dimensions are always expressed as W x H x L . ( Dimensions in mm )
The length is always measured from the frame’s leading edge to the rear edge of the bag.
The bags are always vertical
Frame thickness (T) is usually 25mm

For connection of the duct fans to the channel. The clamp is made of galvanised steel plate and rubber to close tightly and absorb vibrations.
The clamp means that the fan is easy to remove for cleaning and maintenance.

A circular disk valve with an aerodynamically shaped valve cone. With excellent properties in terms of noise level, pressure drop and flow capacity. The design of the sound absorber reduces crosstalk noise. The unit is designed to be mounted on the wall or ceiling. Its design and Moltopren gasket prevent soiling of ceiling and walls.
The diffuser is made of recyclable polypropylene and can tolerate temperatures up to 100° C. The material in the device can also handle most chemicals in small concentrations.
The diffuser is supplied in white as standard.

A poppet valve with aerodynamically designed primary devices. It can be placed on the ceiling or on a wall and has excellent properties in terms of noise, air resistance (pressure drop), air flow and self-damping. The valve design and moltopren packaging prevents contamination of the ceiling and walls. Made with impact resistant white urea and propylene with dirt-resistant surface. The material can withstand temperatures up to 100ºC as well as most chemicals in small concentrations. Standard colour White NCS 0502-Y, gloss 70, corresponding to RAL 9010.

This damper of type IRIS is a precision device for controlling and adjusting air flow in circular ducts. Each damper is individually calibrated to provide the best measurement results. Airflow is obtained by measuring the pressure drop on the diffuser’s fixed measuring nipples and reading the corresponding airflow from the diagram.
Thanks to the central throttling of airflow in the diffuser, the air stream in the duct is even, and the noise level very low.
Can be opened 100%, so it is perfect for installation in ducts that require cleaning.
Made of galvanised sheet steel and provided with adjustment scale and adapters. Conforms to density class C.
White lacquered in RAL9003.

An exhaust valve for ventilation installations requiring low noise even at high pressure drop. Made of sheet steel and electrostatically coated with white epoxy paint. The valve is equipped with a foam rubber ring that seals against the frame. Mounted with mounting frame of type KKT

An exhaust valve made of plate steel, powder-coated in white, RAL 9010, for ceiling or wall installation. The valve reduces duct and fan noise. Airflow is adjusted by turning the conical piece. Can also be used as a supply duct. Installs directly in the duct; can also be installed with a type VLZ mounting frame.

Mounting frame, size 100-160, push-in, for Exhaust air valve.

Mounting frame, size 100-200, push-on, for Exhaust air valve.

Universal valve for use in comfort ventilation systems. Easy to preset to desired pressure drop and quick to adjust. Generates little noise, even during severe pressure drops.
The valve is made from white-lacquered galvanised sheet steel. Spring-encased connection for size 100-160, can be installed in a push-in or push-on mounting frame. Size 200 device is to be installed with a frame of type AKKT 200 or AKKU 200 that has a screw fitting.
