Nonwoven Fabric Filters are filtration devices that use nonwoven fabric as the filtering medium, widely applied in air purification, liquid filtration, and other fields. The main components of a nonwoven fabric filter include a nonwoven filter bag and a supporting frame. Nonwoven fabric (made from synthetic fibers like polypropylene [PP]
The air filter of an air compressor is one of the core components ensuring the normal operation of the equipment. Its primary function is to filter dust, impurities, oil mist, and water vapor from the incoming air into the compressor, preventing damage to internal precision parts. The frequency of replacing
Installation and Usage Instructions for Central Air Conditioning System Air Filters Panel Type Filters, Bag Type Filters 1.1 Air handling units should be equipped with corresponding installation tracks or frames to facilitate filter installation. 1.2 During installation: Filter frame arrows should align with airflow direction V-type filters require vertical orientation

1. Common Ventilation Methods for Residential Fresh Air Systems 1.1 Unidirectional Flow Fresh Air System Working Principle: Only an supply fan is installed to deliver outdoor air into indoor spaces. This creates positive pressure, forcing stale air out through gaps in doors/windows via indoor-outdoor pressure differences. 1.2 Bidirectional Flow Fresh Air
Air Purifier Selection Guide Purification Principles Air purifiers utilize various purification technologies, including: Filtration Adsorption Electrostatic precipitation Photocatalysis Chemical catalysis Negative ion generation Composite methods These methods can effectively remove one or more types of pollutants, such as particulate matter (PM), gaseous pollutants, and microorganisms, from the air. 2. Key
The mesh size (aperture) of flat nylon filter screens is typically customized based on application requirements, but common standard ranges are as follows: 1. Standard Mesh Sizes Mesh Count (Mesh) Aperture Size (μm/mm) Typical Applications 50 Mesh 300~350 μm (0.3~0.35 mm) Coarse filtration (e.g., fruit juice, industrial wastewater) 100 Mesh
Nylon mesh filter is a common air filtration material mainly used to intercept larger particles in the air such as dust, hair, pollen, etc. Nylon Pre-Filter Technical Specifications Core Functions Particle Filtration Captures airborne contaminants ≥5μm (dust, pollen, pet hair, textile fibers) MERV 4-6 rating (per ASHRAE 52.2 standard) Equipment
Primary air filters are suitable for the preliminary filtration of central air conditioning systems, such as the fresh air systems in office buildings and shopping malls, as well as the pre-filtration in electronic factories and food processing workshops. They are also used for air pretreatment in general hospital departments, mainly
