Series 800

FYa (ФЯ) air distributor is designed for providing air exchange in clean rooms of medical institutions, pharmaceutical, electronic, food and other industries.

Design

Structurally an air distributor consists of two hermetically interconnected casings - "lower" and "upper". The upper casing of the air distributor is made of galvanized steel with a polyester coating, and hosts the inlet circular cross-section nozzle. The lower casing is made of an aluminium profile with a polymer coating.

Versions

Air distributors are manufactured with side or top air supply. A shut-off hermetic valve can be mounted into the air distributor, allowing replacement of the air filter without halting the air supply system. The hermetic valve can be adjusted manually from a clean zone or using an electric drive.

To measure differential pressure and perform a filter element leakage test, the air distributor is equipped with connection sockets. The control is carried out from a clean zone or a ceiling void.

The airtightness of the air filter mounting in the air distributor is controlled by a special device. The control is carried out from a clean zone.

Air distribution grill

The air distribution grill can be made as a perforated sheet or a non-adjustable turbulent grill.

Filter

Filters 78 mm deep are installed in the air distributor. Filters class E, H, U according to GOST R EN 1822-1-2010.
