Gel Seal HEPA Box

Introduction

The TKSAGE Gel-Seal HEPA Box sets a new standard for airtight filtration in critical clean environments. Its proprietary gel gasket technology creates a zero-leak seal between the HEPA filter and housing, eliminating bypass airflow that plagues traditional gasketed units. Designed for Class 5 (ISO 14644-1) environments, it delivers 99.999% filtration of 0.3μm particles, making it essential for pharmaceutical, biotech, and microelectronics applications where leakage equals contamination risk.

Scenario-Based Solutions

Sterile Drug Manufacturing

In injectable drug filling rooms, even 0.1% air leakage can introduce microorganisms. This HEPA box installed in HVAC systems uses gel seals to maintain absolute airtightness, complying with USP <800> and EMA guidelines for sterile drug production. PAO leak tests consistently show <0.01% leakage rates.

Stem Cell Research Labs

Stem cell cultures are highly susceptible to contamination. The gel-seal HEPA box provides laminar airflow over culture hoods, with no bypass air to introduce foreign cells or pathogens. Its stable airflow ensures consistent pH and temperature in cell culture media.

Semiconductor Etching Processes

Etching chambers require ultra-clean air to prevent wafer contamination. This HEPA box supplies filtered air to etching tools, with gel seals eliminating particulate ingress through filter-housing gaps—reducing etch defect rates by 35%.

Product Features

Zero-Leak Gel Seal: Thermoplastic gel gasket conforms to housing irregularities; maintains seal through 50+ filter replacements (vs. 10-15 for foam gaskets).

High-Efficiency Filtration: H14 HEPA (99.999% 0.3μm) or U15 ULPA (99.9995% 0.12μm) filter options for ultra-clean requirements.

Pressure Resistant Design: Withstands 500 Pa positive/negative pressure without leakage; ideal for dynamic cleanroom environments.

Easy Maintenance: Tool-less filter replacement; gel gasket reuses with each filter change, reducing waste and costs.

FAQ

Q1: How long does the gel seal last?

A: The gel maintains elasticity for 5 years under normal use (23°C, 40-60% RH) without hardening.

Q2: Can it be used in negative pressure rooms?

A: Yes, the gel seal works equally well in positive and negative pressure environments up to ±500 Pa.

Q3: What’s the filter replacement time?

A: Tool-less design allows filter changes in 15 minutes, minimizing cleanroom downtime.
