SAV fresh air supply valve with a filtering head.
A special knob of the filtering head allows to adjust the air flow. If the valve is installed at height, the adjustment is done with a pull-cord. The valve adjustment is done smoothly up to the full closing. The scale on the filtering head indicates the rate of the valve opening.
Fresh air supply valve is designed for in-wall mounting in residential and office premises. The device prevents dirt and dust intrusion, stops insects and reduces noise level, bringing fresh air into a room.
The necessary duct length is in a range from 400 mm to 1000 mm, with a pitch of 50 mm.
Thermal insulation types
Type 01
Basalt rockwool thermal insulation laminated with reinforced aluminum foil. Possesses better protective properties and has a self-adhesive foil overlap, which simplifies the mounting process.
Type 02
Basalt rockwool thermal insulation. Fire-resistant, non-toxic, transpiring material provides proper sound insulation and does not lose the shape with time.
Type 03
Polyethylene foam thermal insulation. Elastic material with a closed cellular structure possesses better insulating properties and shows high humidity and damage resistance.
Filtering head device
Mounted with round ventilation ducts of 100-125 mm in diameter and used for filtering the air intake. The device also allows to adjust the airflow capacity up to complete cutting the intake off. Adjustment is done by rotating the head. Used in SAV supply valves.
