Side-Access HEPA تصفية الإسكان
A duct-mounted cabinet with removable side doors and a positive-pressure clamping mechanism for servicing HEPA filters from either side.
- Dual-Side Service
- Positive Crank Seal
- Integrated Prefilter Track
- Welded Weatherproof Cabinet
مقدمة المنتج
This housing positions HEPA or ULPA filters perpendicular to the duct and allows them to slide in from either side. A crank or lever mechanism transfers force evenly to each filter gasket, producing a repeatable seal without access from the air face. Removable gasketed doors close both service openings, and an upstream track accepts a shallow prefilter. Standing flanges, pressure taps and challenge ports simplify integration into clean manufacturing and healthcare air systems.
الخصائص الرئيسية
A spring-loaded crank mechanism distributes sealing pressure across each filter row.
The separate prefilter track protects the absolute filter from coarse loading.
External pressure ports support differential-pressure monitoring without opening the cabinet.
مخاوف المنتج للعملاء
A ducted HEPA bank must be serviceable in a narrow plantroom while maintaining uniform gasket compression.
Only one side of the filter bank remains reachable after installation.Removable doors on both sides allow the usable service direction to be selected on site.
Hand-tightened clips apply unequal pressure around a large HEPA gasket.The crank mechanism applies coordinated sealing force across the filter row.
Coarse dust shortens expensive HEPA filter life.An integral prefilter track captures larger particles before the final filter.
A door seal leaks after repeated maintenance cycles.Square reinforced doors and high-memory perimeter gasketing maintain contact around the opening.
