(CAP18WFBHR)
Click image to enlarge
The CAP18WFBHR HEPA-filtered pass-through chamber is a fully welded, wall-mounted, recirculating pass-thru unit. It is designed for aseptic manufacturing applications requiring sterile yet easy cleaning. The unique double-wall construction design encases and protects the built-in mechanical interlock while facilitating easier cleaning. A motorized HEPA filtration system recirculates air through integrated returns, maintaining cleanroom standards by removing at least 99.99% of airborne particles 0.3 micrometers (µm) in diameter. Durable construction and a secure sealing system help maintain a controlled cleanroom environment while supporting efficient material transfer.

A recirculating HEPA filtration pass-thru is ideal for applications requiring a continuous, contaminant-free environment. By recirculating the interior air, airborne particles are rapidly removed by successive passes through the HEPA filter. Recirculation also minimizes pressure buildup that can cause leakage into an adjacent positive-pressure cleanroom. For our product, the integrated HEPA filter unit continuously recirculates filtered air through air returns incorporated into the side walls.Recommended Applications
