Liquid-Tank Sealed HEPA Supply Air Outlet

Product Overview

The Liquid-Tank Sealed HEPA Supply Air Outlet (gel seal HEPA box) is a high-performance air supply solution specifically designed for the air supply end of biological cleanrooms. It integrates a replaceable HEPA filter with a gel seal design, ensuring exceptional airtightness and compliance with pharmaceutical regulatory agency validation and testing requirements. Constructed with electrostatic spraying cold-rolled steel plate or stainless steel, the cabinet boasts a sleek appearance and strong corrosion resistance. Available in four models (ZKSJ-GF 01 to 04) with rated air volumes ranging from 500 to 2000 m³/h, it delivers uniform, high-purity air, making it a preferred choice for well-known pharmaceutical companies and biological cleanrooms.

Scenario-Based Solutions

Pharmaceutical Cleanroom Air Supply

In pharmaceutical production cleanrooms (e.g., API manufacturing, sterile dosage form production), the gel seal design eliminates air leakage, ensuring that only HEPA-filtered air (≥99.97% efficiency for 0.3μm particles) enters the production area. This maintains ISO Class 5 or higher air quality, complying with GMP and FDA regulations. The stainless steel cabinet resists corrosion from cleaning agents and disinfectants, supporting strict hygiene protocols.

Biological Laboratory Ventilation Systems

For biological safety laboratories (BSL-2/3) and research facilities handling sensitive samples, the air outlet provides contaminant-free air supply, protecting experiments from airborne pollutants. The uniform fuming via the top ring pipe ensures consistent air distribution, while the easy-to-replace HEPA filter minimizes downtime during maintenance, supporting continuous research operations.

Medical Device Manufacturing Cleanrooms

Medical device factories require ultra-clean air to prevent product contamination. This HEPA supply air outlet delivers stable, high-purity air, meeting the strict air quality standards for Class II/III medical devices. The electrostatic spraying surface is easy to clean and disinfect, aligning with the hygiene requirements of medical device production environments.

FAQ

Q1: What materials are available for the cabinet, and how to choose?

A1: The cabinet is available in electrostatic spraying cold-rolled steel plate (cost-effective, suitable for general cleanrooms) and stainless steel (corrosion-resistant, ideal for pharmaceutical or humid environments requiring frequent disinfection). Choose stainless steel for GMP-compliant pharmaceutical facilities or environments with aggressive cleaning agents; cold-rolled steel is suitable for standard cleanrooms with moderate hygiene requirements.

Q2: How often should the HEPA filter be replaced?

A2: The HEPA filter has a typical service life of 1 to 3 years, depending on operating conditions (air volume, dust load, and pre-filtration efficiency). We recommend regular filter integrity testing (every 6 to 12 months) and replacement when the filter fails the test or the pressure drop exceeds the design limit (usually 250-300Pa).

Q3: Is the product compliant with pharmaceutical regulatory requirements?

A3: Yes, the product is fully compliant with validation and testing requirements of pharmaceutical regulatory agencies (e.g., FDA, EMA, NMPA). It is equipped with PAO/DOP test ports for filter efficiency verification and provides comprehensive documentation (including material certificates, test reports, and installation records) to support GMP compliance audits.
