Ceiling-معلقة صفحية تدفق هود
An overhead HEPA-filtered hood suspended above process equipment to create a defined downward clean-air zone without floor-mounted supports.
- Floor-Free Suspension
- Overhead HEPA Downflow
- Adjustable Hanging Height
- Optional Flexible Curtains
مقدمة المنتج
The suspended hood mounts from the building structure above a filling point, inspection table or compact process machine. A rigid supply plenum distributes HEPA-filtered air through the lower diffuser, while adjustable threaded hangers set the operating height and maintain level. Optional clear curtains extend the protected zone without permanent walls. Structural loads, electrical routing and service clearance are coordinated above the ceiling, leaving the floor around the process accessible.
الخصائص الرئيسية
A pressure-equalizing plenum supplies the complete lower diffuser evenly.
Height-adjustable hangers accommodate equipment and ceiling variations.
Flexible clear curtains can limit cross-drafts around selected sides.
A hinged or lift-down filter panel allows service from the clean side when required.
مخاوف المنتج للعملاء
An overhead hood must deliver an even clean-air footprint while remaining structurally secure and serviceable above operating equipment.
Floor legs obstruct carts and cleaning around the process.Ceiling suspension leaves the floor perimeter open.
An uneven hanging frame tilts the airflow diffuser.Individually adjustable hangers allow the plenum to be leveled after installation.
Room cross-drafts shorten the protected downflow zone.Optional clear curtains extend from the hood edge around the critical process area.
Filter replacement conflicts with equipment below.A selected top-service or clean-side lift-down arrangement matches the available access route.
