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
Pleated Panel Air Filter is a device that increases filtration area through folded filter media (such as polyester fiber, metal mesh, etc.). Its core advantages are “low initial resistance and high dust holding capacity,” capable of capturing large particle pollutants like dust and hair above 10 microns (μm). It is
Technical Specification: Pleated Panel Air Pre-Filter 1. Structural Composition 1.1 Filter Media Material Construction: Polyester fiber, fiberglass, or non-woven synthetic fabric, precision-folded in sinusoidal waveform (accordion configuration) to maximize surface area (3-5× expansion vs. flat-panel designs). Geometric Parameters: Fold depth: 20-100mm Pleat pitch: 5-20mm 1.2 Support Framework Primary Materials: Extruded
What is an Air Filter? An air filter is a device used to purify air. It is commonly used in clean rooms, laboratories, operating rooms, and for dust prevention in electronic equipment. Depending on their filtration efficiency, air filters are divided into primary filters, medium-efficiency filters, high-efficiency filters, and ultra-high-efficiency
I. Understanding 3 Critical Filter Types for Cleanrooms 1. Primary Filters – First Defense Against Macroparticles Function: Capture visible contaminants (dust >10μm, hair, fibers) Key Features: Washable synthetic fiber media (typically G4/F5 grade) Initial pressure drop <50 Pa at 2m/s face velocity 2. Medium-Efficiency Filters – Intermediate Protection Performance: Arrestance:
