In-Situ Scanning Biosafety HEPA Filter








The instrument is mainly used for contaminated air treatment exhausted by negative pressure isolation environments, e.g., high-level biosafety laboratories, negative pressure isolators, etc. It consists of main body, HEPA filter, scanning and leakage detection mechanism, in-situ sterilization port, control cabinet and so on. With functions of in-situ leakage detection and sterilization, HEPA filter meets requirements of GB19489-2008 Laboratories-General requirements for biosafety.

Composed of plenum chamber, HEPA filter, in-situ leakage detection and sterilization mechanism, pressure difference gauge, etc.

Adopt anti-leakage structure, welded by high-quality stainless steel, and all welds are treated in a special way to ensure tight sealing. Minute leakage rate is not more than 0.1% of net volume under±1000Pa pressure.

No permanent structural deformation under -2500Pa pressure for 60min, pressure-resistant ability meets requirements.

Two filter sealing methods are available: gasket sealing or liquid tank sealing.

Vertical and horizontal types are available.

Air volume 500 m³/h, 1000 m³/h, 1500 m³/h, 2000 m³/h are available.

Equipped with in-situ scanning leakage detection mechanism and dust particle sampling port, convenient for HEPA filter leakage detection.

Adopt scanning method for leakage detection. Scanning area covers air outlet of filter and joint between filter and frame without dead corners.

Effectively identify and accurately locate leakage points.

Control cabinet is designed with status monitoring device, which can accurately monitor scanning path, automatically issue and one-button export reports.

Equipped with sterilization test and verification to meet requirements of sterilization effect verification.

Equipped with pressure sampling port, which can be used to install pointer differential pressure gauge or pointer differential pressure transmitter (optional) for monitoring resistance of HEPA filter.

With a unique identification code for each set.
