HEPAbox Plenum Box for Cleanrooms

A high-hygiene terminal air distribution unit for demanding cleanroom environments. It integrates a HEPA H14 filter within a fully welded stainless steel housing to deliver ultra-clean, laminar airflow for critical applications in healthcare, pharmaceuticals, and laboratories.

Product Description

Key Features & Benefits

Hygienic Stainless Steel Construction
All-welded AISI 304 stainless steel housing. Eliminates seams, ensures airtightness, and facilitates cleaning/disinfection.
Integrated HEPA Filtration
Includes a high-efficiency H14 class HEPA filter (AAF brand) as standard, providing >99.995% particle removal.
Compliant with Critical Standards
Designed and certified per VDI 6022, DIN 1946-4, ÖNORM H 6020 for hospital and lab HVAC hygiene.
Service-Friendly & Airtight
Features an internal shut-off damper (class 4) to isolate the unit during safe filter changes from inside the room.
Low Noise & High Performance
Engineered for low noise emissions and high airflow up to 1440 m³/h with minimal pressure loss across the filter.

Diffuser Front Panel Options Comparison

Diffuser Type	Key Flow Pattern	Best For / Application	Material (Standard)
VVPM Whirling Anemostat	Swirling, turbulent flow for intensive air mixing.	General air distribution in cleanrooms, good for mixing.	Stainless steel, mild steel, or aluminum.
DVCM Perforated Panel	Multiple small jet streams, even distribution.	Low-velocity, draft-free supply in highly sensitive areas.	Aluminum sheet.
VNM Adjustable Grille	Adjustable blades for directional control.	Areas where airflow direction needs periodic adjustment.	Aluminum profiles (anodized).
RAG45 Fixed 45° Grille	Fixed 45° blade angle for deflected, non-linear flow.	Perimeter zones or specific airflow direction requirements.	Aluminum profiles (anodized).
SMM Fixed Vertical Grille	Vertical, straight blades for linear discharge.	Simple exhaust or supply where direction is not critical.	Aluminum profiles (anodized).
