Modular Clean Room

Pleatless HEPA Filter with Liquid Sump

The liquid-trough filter combines the ultra-low resistance and high dust-holding capacity of a pleatless design with the ultimate airtightness of liquid-trough sealing. Its advantages include: zero leakage risk (ensuring the highest cleanliness), low energy consumption (reducing operating costs), and a slim profile for easy installation. It is the most reliable choice for microelectronics, pharmaceuticals, and other industries requiring ISO Class 5 or higher environments.

Features:

Zero-Leak Sealing:Liquid-trough sealing achieves maximum airtightness.
Ultra-Low Operating Resistance: Partition-free design significantly reduces energy consumption.
Ultra-Thin High Efficiency: Increased filtration area facilitates FFU installation.
High Dust Holding Capacity: Extends service life and reduces maintenance frequency.
Suitable for Highest Cleanliness Zones: Specifically engineered for ISO Class 5 and higher environments.

Enqury Now

In critical industries with extremely high cleanliness requirements, even the smallest leak can lead to catastrophic consequences. What you need is not just high-efficiency filtration, but absolutely reliable airtightness.

boben Modular Cleanroom Manufacturers are engineered to meet the most stringent cleanliness demands. We introduce our premium Gel-Seal Mini-Pleat HEPA/ULPA Filter. This product seamlessly integrates next-generation pleatless technology with the most reliable sealing solution, serving as the ultimate safeguard for your ultra-cleanroom systems.

The liquid-trough, non-partitioned high-efficiency filter represents the pinnacle of air filtration technology. It combines two core advantages:

1.Mini-Pleat Design:

By replacing traditional pleat separators with hot-melt adhesive lines, our filters achieve higher pleat density. This means:

Ultra-low resistance: Significantly reduced airflow resistance, saving over 30% in fan energy consumption and substantially lowering your long-term operating costs.
High Dust Holding Capacity: Extends filter lifespan while minimizing downtime for maintenance.
Lightweight and Easy Installation: Particularly suited for FFU (Fan Filter Unit) systems with limited ceiling space.

2.Liquid Groove (Gel-Seal) Sealing Technology:

This is the key to ensuring zero leakage. Traditional gasket seals may develop minute gaps due to uneven installation or gasket aging.

The gel-seal utilizes a groove filled with a specialized gel compound. When the filter frame’s “knife-edge” structure is immersed in the gel, it forms a 360-degree seamless, flexible seal.
This eliminates all potential leakage paths, ensuring only clean air passing through high-efficiency filter media (HEPA/ULPA) enters your workspace.

FAQ

A: Boben has 14 years of professional experience in R&D, production and sales of modular cleanrooms. As a seasoned foreign trade manufacturer, our business covers Southeast Asia, the Middle East, Europe, Africa and other regions. We deeply understand the local industry standards, certification requirements and market needs of different countries, and have served hundreds of B-end customers including electronics, pharmaceuticals, food processing and laboratories overseas.

A: Our modular cleanrooms cover ISO 1 to ISO 9 (equivalent to Class 100 to Class 100,000) cleanroom classes. They are widely applicable to electronics & semiconductor manufacturing, biopharmaceuticals, medical devices, food sterile processing, precision laboratory research and other scenarios. Each set of products is designed according to the unique process requirements of different industries, such as temperature/humidity control, anti-static design, and microbial pollution prevention.

A: Yes, customization is our core advantage! Based on 14 years of technical accumulation, we can tailor solutions according to your actual needs: ① Cleanroom class (ISO 1-9) and space size; ② Core configurations (HEPA filter system, air circulation mode, constant temperature & humidity system, intelligent monitoring); ③ Material selection (stainless steel, color steel plate, aluminum honeycomb panel, etc.); ④ Compliance with local standards (such as FDA, GMP, CE, etc.). We will provide one-stop customized services from scheme design to final delivery.

A: Absolutely! All our products strictly comply with international standards such as ISO 14644 (cleanroom classification) and ISO 14698 (biological contamination control). We have passed multiple international certifications, and the delivered cleanrooms can smoothly pass third-party testing and certification required by target markets (such as FDA for the US, GMP for the EU, and local certification standards in Southeast Asia/Middle East). We will provide complete technical documents and test reports to assist you in customs clearance and market access.

A: The production cycle is 2-4 weeks for standard configurations and 4-6 weeks for customized solutions (faster than the industry average). For overseas transportation, we cooperate with well-known logistics companies to provide sea/air shipping options, and professionally package modules to avoid damage during transportation. On-site installation is simple and fast—we provide detailed installation drawings, video guidance, and can dispatch technical teams to overseas sites if required. The entire installation process can be completed in 1-2 weeks, helping you put into production quickly.

A: We provide global after-sales service with no worries: ① 1-year warranty for core components (HEPA filters, control systems, etc.), and lifelong maintenance services; ② 24/7 online technical support (via email, phone, video call) to solve problems in a timely manner; ③ Spare parts supply guarantee—we have cooperative warehouses in key regions to ensure fast delivery of spare parts; ④ Regular follow-up visits to understand the operation status of cleanrooms and provide optimization suggestions.
