No External Ductwork
Front Service Access
Timed Internal Purge

مقدمة المنتج

This compact filtered pass box combines blower, prefilter, final filter and controls in a removable service cassette. With both doors locked, it recirculates the enclosed chamber volume and can automatically start a purge after loading. A wall trim system closes the finish opening on both room faces, supporting cleanroom retrofit work.

الخصائص الرئيسية

The removable cassette groups fan, filtration and controls in one service assembly.

The chamber operates from a local electrical connection rather than supply and return ducts.

Front-facing service access suits installations with limited overhead clearance.

A timed clean-air cycle starts after the loading door shuts.

Adjustable trim frames accommodate different wall thicknesses.

مخاوف المنتج للعملاء

Retrofit transfer points need active air cleaning despite limited services and constrained maintenance access.

The existing wall has no path for new HVAC ductwork.An integral recirculation cassette uses only local electrical power.

Ceiling obstacles prevent top-mounted service.The cassette can be removed from the accessible service face.

Operators open the clean side before an internal purge.The controller times the purge and withholds door release.

Wall cut-outs leave difficult-to-clean perimeter gaps.Adjustable stainless trim clamps and seals the opening on both faces.
