العادم HEPA تصفية الإسكان
A sealed wall or ceiling housing that captures contaminated room exhaust through a room-side replaceable HEPA filter before it enters the duct system.
- Negative-Pressure Service
- Room-Side Replacement
- Optional Prefilter Door
- Integrated Test Connections
مقدمة المنتج
The exhaust HEPA housing mounts at the room boundary so contaminated air crosses the filter before entering shared ductwork. A welded box, sealed inlet grille and compression clamp keep the dirty side confined to a shallow room-side zone. The front panel can include an integral prefilter and opens for filter replacement without disturbing the downstream duct. Pressure sampling, aerosol injection and scan access can be incorporated around the sealing frame.
الخصائص الرئيسية
Room-side filter access supports service where ceiling-void entry is restricted.
A hinged prefilter face intercepts lint and extends the life of the HEPA element.
Integrated test connections allow seal and resistance checks at the terminal.
مخاوف المنتج للعملاء
An exhaust terminal must prevent contaminated room air from bypassing into the common duct and remain serviceable under negative pressure.
Contaminants enter the duct before reaching a remote central filter.A terminal HEPA element captures particles at the room boundary.
Lint loads the HEPA face and raises room negative pressure.A removable coarse prefilter intercepts larger debris ahead of the absolute filter.
The sealing edge cannot be inspected from the occupied space.Room-side clamps expose the gasket or gel interface after the grille is removed.
Testing disturbs ductwork shared with adjacent rooms.Local pressure and aerosol ports keep verification focused on the individual terminal.
