Purification equipment

Featured products

Purification equipment refers to specialised systems designed to remove unwanted particles, contaminants, microorganisms, chemicals, and other impurities from air, gases, water, and process fluids. These systems are designed to improve the cleanliness and quality of the treated medium, helping to maintain controlled conditions in industrial and commercial environments.

Depending on the required level of purification, the equipment may include air purification systems, gas purification units, water purification systems, sterilisation equipment, adsorption systems, filtration units and other related treatment equipment. Different technologies can be used individually or in combination to achieve the required level of purification.

Medium-efficiency filter

Bag filters with anodised aluminium frame (or galvanised steel, SUS, ABS), internal support grids, and adhesive sealing. Synthetic fibre or glass fibre media. Ultrasonic welding and reinforced grids for uniform airflow. Available in M5–F9 (EN 779). Multiple frame materials, specifications, and construction options available.

Pre-filter

These pre-filters feature anodised aluminium profile frames that are lightweight, strong, dust-free, and easy to install. The protective mesh is made from high-quality galvanised steel, rust-resistant, dust-free, and reusable. The filter media is made from high-quality polyester synthetic fibres, offering high filtration efficiency, large dust-holding capacity, and can be washed and reused. Available in G1 to G4 efficiency grades (EN 779). Various frame materials, specifications, and construction methods are available for selection.

High-efficiency filter

These high-efficiency filters feature an anodised aluminium frame, eco-friendly polyurethane sealant, and a powder-coated steel grille. The filter media is ultra-fine water-resistant glass fibre paper. Available in HEPA (H13–H14) and ULPA (U15–U17) grades per EN 1822. Low-VOC hot-melt adhesive ensures even airflow and strong bonding. Various frame materials and specifications are available.

Applications of Purification Equipment

  1. Pharmaceuticals and biotechnology

Used to control contaminants in pharmaceutical production, laboratories, and sterile areas where high cleanliness standards are required.

  1. Food and beverage processing

Used to purify process water, air, and other production media to support hygienic processing and consistent product quality.

  1. Electronics and semiconductor manufacturing

Used to control airborne particles and other contaminants in clean rooms and precision manufacturing environments.

  1. Industrial manufacturing

Used to treat process air, gases, water, and other fluids to help protect equipment and maintain cleaner production conditions.

  1. Water and environmental treatment

Used to treat drinking water, process water, wastewater, and other liquid streams by removing suspended solids, chemicals, microorganisms, and other impurities.

Why Is Purification Equipment Needed?

Purification equipment is required to eliminate contaminants that could impact product quality, equipment performance, process stability, or environmental conditions. In industries with strict cleanliness requirements, effective purification is essential for maintaining controlled production environments.

It can also protect sensitive equipment and downstream processes by reducing particles, chemicals, microorganisms, and other impurities before they enter critical systems. The appropriate purification technology should be selected based on the type and concentration of contaminants, treatment capacity, required purification level, operating conditions, and applicable industry requirements.
