Gel Seal HEPA Filter

Product Description

The Gel Seal HEPA Filter is a high-efficiency air filtration unit specifically designed to provide a superior air-tight seal in critical environments. Instead of traditional gaskets, it utilizes a non-hardening gel channel that ensures a leak-free fit when installed in compatible housings. This gel seal system eliminates bypass leakage and guarantees consistent filtration performance of ‰99.97% at 0.3 microns, making it ideal for demanding applications requiring the highest air purity standards.

Key Features:

• Filtration Efficiency: ‰99.97% at 0.3 microns (available in H13, H14 per EN1822)

• Seal Type: Gel-filled channel for airtight sealing (polyurethane or silicone-based)

• Media: Micro-glass fiber filter media with mini pleat construction

• Frame Options: Aluminum, stainless steel, or galvanized steel

• Gel Compatibility: Designed for knife-edge housing systems

• Faceguard: Optional expanded metal or protective screen

• Standard Sizes: Available in standard and custom dimensions

• Applications: Cleanrooms (Class 1“100,000), pharmaceutical facilities, biosafety cabinets, hospitals, semiconductor production, isolators

Frequently Asked Questions (FAQs)

1. What is a Gel Seal HEPA filter?

A Gel Seal HEPA filter is a high-efficiency particulate air filter designed with a gel-filled perimeter channel that forms an airtight seal with a knife-edge housing, eliminating the risk of air bypass.

2. Why choose a gel seal over a gasket seal?

Gel seals provide superior leak-proof performance, especially in high-spec environments like cleanrooms and pharmaceutical areas where any bypass could lead to contamination. They are easier to install and ensure uniform sealing pressure.

3. Where are Gel Seal HEPA filters typically used?

These filters are common in cleanrooms, biosafety cabinets, laminar flow units, isolators, pharmaceutical processing, and hospital surgical suites”anywhere where 100% leak-free sealing is critical.

4. What is the lifespan of a Gel Seal HEPA filter?

Typical service life ranges from 1 to 3 years depending on usage, airflow rates, and environmental cleanliness. Pressure drop should be monitored regularly to determine optimal replacement time.

5. How is the gel seal maintained?

The gel is self-healing and does not harden over time. It requires minimal maintenance. However, it should be kept clean and protected from mechanical damage or drying due to environmental exposure.

6. Can Gel Seal filters be reused?

The filter media is not washable or reusable. However, the gel seal can withstand multiple insertions if handled carefully. Filters must be replaced once performance degrades.

7. How is the filter tested?

Each unit is factory tested for leakage and efficiency using methods such as PAO (Polyalphaolefin) aerosol or DOP (dioctyl phthalate) scan testing, in compliance with EN1822 or IEST standards.

8. Are custom sizes or materials available?

Yes, manufacturers typically offer custom configurations including different sizes, frame materials, gel types, and filter grades to suit specific applications and housings.
