 High-efficiency filters with an upper liquid chamber seal were sent by road to a pharmaceutical company for the modernization of sterile clean workshops according to GMP standards 

2026-07-08

Recently a batch of specialized pharmaceuticalhigh-efficiency filters with upper liquid chamber sealassembled in a dust-free environment, tested for leaks using the PAO method, moisture-proof packaging, carefully packed into trucks and shipped to a large domestic pharmaceutical company for a sterile dosage form workshop modernization project. These high efficiency top liquid chamber seal filters provide zero air leakage due to the top liquid chamber seal design, are suitable for high cleanliness areas such as filling areas, buffer rooms, quality control laboratories and consistently meet GMP sterile manufacturing acceptance requirements, creating a key filtration barrier for sterile air control throughout all stages of drug production.
Ready-to-install HEPA filter with special gel seal for pharmaceutical cleanroom ceiling systems; Features a built-in blue gel seal and low-dust fiberglass filter media; Compatible with air purification systems for Class 100 and Class 10,000 sterile clean areas.
I. Context of the modernization of the project: the stringent requirements of pharmaceutical workshops for hermetic filtration without leaks
The collaborating pharmaceutical enterprise has several production lines of sterile injectable and oral dosage forms. Previously used high-efficiency filters had a complex on-site installation procedure, and the small service space under the suspended ceiling created challenges: when replacing filters, air circulation in the clean area was easily disrupted, resulting in exceeding microbial and particulate limits on the shop floor, risking drug contamination and entire product batches being scrapped.
The air purification company's engineering team compared several models of high-efficiency filters and formulated three main purchasing criteria:
  1. Top fluid chamber seal design compatible with small overhead service hatches; replacing the filter does not require complete dismantling of the suspended ceiling panels;
  2. Filter material with low volatility and low release of fibers, without the release of harmful substances, meets the standards of sterile pharmaceutical production;
  3. Each filter is fully PAO leak tested in-house and each product comes with a test report for archiving and GMP testing.
After multiple seal leak simulation tests, the customer selected our high-efficiency top seal liquid chamber filters as the primary filtration equipment for a facility retrofit, with a batch of products installed in the ventilation systems of sterile filling facilities, raw material buffer rooms, and microbiological control laboratories.

II. Key Benefits of High Efficiency Top Seal Filters for Pharmaceutical Applications

Deliveredhigh-efficiency filters with upper liquid chamber seal have been specifically optimized for the design of suspended ceilings in pharmaceutical cleanrooms, and their numerous performance characteristics meet stringent GMP manufacturing requirements:
  1. Top fluid chamber seal design – easy installation and replacement where ceiling space is limited

    The top of the equipment is equipped with a one-piece blue chamber for liquid sealing. When installed in place, liquid silicone is poured into the chamber, forming a seamless sealed layer that completely eliminates gaps for air leaks around the perimeter of the frame. Unlike traditional side fluid chamber filters, the top seal design is suitable for small service ceiling spaces. To replace the filter element, simply open the top service hatch without dismantling the suspended ceiling frame. This significantly reduces the time it takes to stop production to modernize a clean shop and reduces losses from interrupting the production of medicines.

  2. Ultra-fine glass fiber filter material with low dust emission - prevents re-contamination of medications

    Inside, a dense filter material made of ultra-fine glass fiber is used, which stably provides the required efficiency of retaining suspended particles of 0.3 microns in size, effectively retaining bacteria, spores, and dust aerosols in the air. Before leaving the plant, the filter material is cleaned from dust in a dust-free room, during operation it does not emit fibers and volatile organic compounds (VOCs), eliminates cross-contamination of raw materials and finished dosage forms, and complies with sterile pharmaceutical control standards.

  3. Lightweight aluminum alloy frame, corrosion resistant - suitable for workshops with constant temperature and humidity

    The one-piece aluminum alloy frame with anti-oxidation surface treatment does not rust or deform during long-term operation in workshops with temperatures of 18–26 °C and relative humidity of 45–65%. The frame is equipped with locking locks, allowing one technician to hang and position the filter, reducing labor costs for on-site installation.

  4. Comprehensive PAO Leak Testing – Fully Compliant with Factory Testing Regulations

    Each filter is leak tested with a PAO aerosol in a Class 10,000 dust-free environment, leak data for each product is recorded, and complete test reports are included with the filters. This simplifies inspections according to the GMP standard and archiving of documentation by pharmaceutical enterprises, eliminating risks during inspections by regulatory authorities.

    The HEPA filter with gel seal has undergone a sealing process and is shipped directly to the pharmaceutical company's facility where they are renovating their sterile facility.
