Liquid (Trough) Gasket HEPA Supply Outlet: Precision filtration safeguards cleanliness.
Core Structure
1.Box: Constructed from cold-rolled steel plate, with electrostatic powder coating. Stainless steel is available as a custom material. It is corrosion-resistant and high-strength. Welds are sealed to prevent leakage.
2.Liquid Tank Sealing System: The core components include a sealant tank and high-viscosity sealant. The filter frame is embedded in the box's edge to form an airtight seal. The sealant does not stick during replacement, ensuring long-term sealing performance.
3.High-Efficiency Filter: Equipped with ultra-fine glass fiber or PTFE membrane filter media, achieving a filtration efficiency of over 99.99% for MPPS (Most Penetrating Particle Size), with some models reaching up to 99.9995%.
4.Auxiliary Components: Includes a plenum chamber, diffuser, butterfly valve, and regulating device. The plenum chamber stabilizes airflow, the diffuser ensures uniform air delivery, and the valve allows for easy adjustment of the airflow.
Core Advantages
1.Zero-Leakage Seal: The liquid sealing medium can fill even the smallest gaps, with a leakage rate as low as 0.001%. It is unaffected by vibration, temperature, or humidity changes, preventing unfiltered air from seeping in.
2.High-efficiency clean air supply: Filtration precision meets Class 100 and above cleanroom requirements, effectively intercepting dust, bacteria, viruses, and other pollutants ranging from 0.1-0.3μm.
3.Uniform and stable airflow: Pressure equalization in the plenum chamber and diffusion via the diffuser ensure uniform airflow velocity, eliminating dead zones and guaranteeing consistent indoor cleanliness.
4.Convenient maintenance: Supports top or side mounting; filters can be replaced directly from the ceiling without disassembling the enclosure. Testing cycles can reach up to 2 years, reducing maintenance costs.
5.High durability: The sealant is resistant to chemical environments with a pH of 2-12 and maintains elasticity within a temperature range of -20℃ to 80℃, resulting in a long service life. The enclosure material is adaptable to complex operating conditions.
Working principle:
Air first enters the plenum chamber for pressure equalization and stabilization, then undergoes precise filtration through the high-efficiency filter, where pollutants are intercepted and adsorbed by the filter media. The liquid-sealed system completely prevents leakage, ensuring that only clean air passes through the diffuser, delivering a uniform airflow into the room and maintaining the cleanliness level of the space.
Applicable Scenarios:
Widely used in places with strict requirements for air cleanliness and airtightness, such as hospital operating rooms, biopharmaceutical workshops, semiconductor manufacturing plants, LCD panel production lines, precision laboratories, and clean food processing areas, adaptable to the controlled environment requirements of different cleanliness levels.
