Gel-seal HEPA supply outlets

HEPA supply air outlets with a gel-seal channel that locks the filter frame against the housing knife edge for a leak-tight seal, in top-feed and side-feed versions with an optional regulating damper.

Description

A gel-seal HEPA supply outlet (gel-seal HEPA box) delivers filtered air into high-cleanliness spaces through a HEPA filter seated in a liquid gel channel. The filter frame sits in a gel potting groove that mates with the knife edge around the housing, forming an airtight seal and preventing bypass leakage; because the gel does not stick to the knife edge, the filter can be pulled and replaced from below the ceiling without dismantling the housing, which keeps maintenance time and cost down. The diffuser plate and filter are easy to remove and refit. The source rates filtration of 0.3 um and larger particles at 99.99%. Outlets are available in top-feed and side-feed versions; five sizes in each cover airflows from 500 to 3000 m3/h at an average velocity of 0.9-1.1 m/s, and a regulating damper can be fitted as an option.

Features

  • Gel-seal channel with housing knife edge: airtight seal and no bypass leakage.
  • Filter replaced from below the ceiling without removing the housing; gel stays off the knife edge.
  • Filtration of 0.3 um and larger particles rated at 99.99%.
  • Top-feed and side-feed versions; five sizes each covering 500-3000 m3/h.
  • Optional regulating damper for airflow balancing.

Applications

  • Hospitals and biological pharmaceutical clean areas
  • Semiconductor and LCD manufacturing
  • Precision machinery and optics production
  • Terminal supply air for high-cleanliness ventilation systems

The source image lists two sub-tables; they are merged here with a feed-type column. C models are top-feed, D models side-feed. Values that appear once across all models are repeated on each row. Source model codes carried a factory series prefix that was removed; C01-C05 and D01-D05 are size classes, not yet confirmed type designations. A regulating damper is optional.
