Particle Filter

Guangdong Biaodian supplies high-quality particle filter for various demanding industrial dust removal and air filtration systems. This filter unit is designed as a complete product and can be installed directly into equipment.

In use, air passes through the densely pleated filter media, and particles are securely held inside, so fewer contaminants enter downstream sensitive equipment. Compared with raw materials, this finished cartridge features a built-in support mesh and exterior reinforcement for a stable structure. Furthermore, the media surface undergoes deep water and oil repellent treatment, making it easier to install and replace while exponentially extending its service life. It can be used as a standalone filter or as a pre-filter together with finer filtration stages.

Product Definition

Particle filter is a specialized industrial-grade finished air filter utilizing a cylindrical pleating process. The core nonwoven filter media is professionally treated to be hydrophobic and oleophobic. Supported by internal and external metal meshes and high-strength straps, it provides a massive filtration area within a limited volume while perfectly resisting moisture and oil mist. It is the ideal consumable for handling high-concentration mixed dust and protecting large core machinery.

Core Selling Points

Water & Oil Repellent: The special surface treatment gives the media excellent hydrophobic and oleophobic properties. In conditions with high moisture or oil mist, dust cannot form sticky cakes on the surface, vastly improving the efficiency of pulse-jet cleaning.

Massive Dust Holding Area: The tight pleating process significantly increases the effective filtration area, lowers the face velocity, and boosts the overall dust holding capacity.

Rock-Solid Structure: The combination of an internal metal support mesh and external anti-expansion straps ensures the cartridge will not collapse or tear under high pressure drops or powerful pulse cleaning.

Excellent Depth Filtration: When air passes through the cartridge, larger particles are stopped on the surface, while smaller ones are captured inside the media during airflow.

Applications & Use Cases

This cartridge is built to handle extremely complex intake and dust collection conditions and is usually installed at the front or middle stage of an air filtration system.

High Humidity/Oily Dust Environments: Machining centers (CNC), metal cutting, and welding fume extraction workshops prone to moisture and oil mist.

Large Power Equipment Intake: Pre-filtration for air compressors, blowers, and gas turbines in humid coastal areas or rainy climates.

Quality Assurance & Factory Control

As a direct manufacturer, we do more than just assemble the physical cartridge. Before leaving the factory, every batch of core filter media must pass strict hydrophobic and oleophobic performance tests. Over time, dust builds up inside the filter, which can improve filtration to some extent but will also increase resistance. Thanks to the water and oil repellent properties, we ensure that the initial resistance and operational resistance remain highly controllable even in harsh environments.

Why Choose Us?

True Source Manufacturing: We are a physical factory that formulates our own nonwoven fabrics. The water and oil repellent treatment is deeply integrated during the material forming stage, rather than just a simple surface spray, ensuring durability that far exceeds standard OEM products on the market.

Long-Lasting & Energy Efficient: Standard filter paper easily loses permeability when exposed to water and oil, causing a sudden surge in fan load. Our repellent cartridges maintain excellent breathability long-term, saving significant energy and replacement costs for you or your customers.

Installation & Operational Guidance

Installation Guide: During installation, make sure the airflow direction is correct and sealing on the end caps is proper to avoid air bypass.

Maintenance Advice: Despite its excellent anti-blinding performance, the filter should be checked regularly based on pressure drop or working time. When resistance increases irreversibly or performance drops, replacement is recommended.

Packaging & Shipping

Because industrial bulk goods may encounter high-humidity environments during long-distance transit, we use independent packaging with moisture-proof thick inner bags and high-strength corrugated boxes. Bulk orders are standardized with pallet packing and stretch film reinforcement, ensuring the cartridges are free from deformation and ready for installation immediately upon arrival.

FAQ

Q1: Our dust contains moisture and cutting fluid vapor, and standard cartridges clog up in days. Will this work?

A: Absolutely. This product is designed exactly for your conditions. The water and oil repellent treatment prevents moisture and oil droplets from forming a film on the media. The dust remains dry and is easily blown off by the pulse-jet system, completely solving the "blinding" issue.

Q2: Can it be cleaned and reused?

A: In equipment with pulse-jet cleaning systems, it automatically cleans surface dust using compressed air. However, for manual physical cleaning, to maintain the stability of the internal structure, it is mostly recommended to be replaced once it reaches its operational lifespan.

Q3: Will the water and oil repellent treatment affect the original air permeability (airflow resistance) of the cartridge?

A: No. We use advanced surface modification technology to form a nano-level protective layer on the fibers without altering the original porous structure of the nonwoven fabric. It maintains extremely low initial resistance and high permeability while offering excellent repellent properties.

Sample Support & Warranty

Facts speak louder than words. For difficult conditions like high humidity and oil, samples can be provided for testing directly on your machines. If there is a severe drop in air permeability or a dimensional mismatch under agreed conditions, we offer full technical support and return/exchange guarantees.

Customization & OEM Process

Equipment intake cabins vary greatly, and we support high-level customization.

Full Customization: Size and structure, end cap materials, and the required level of water/oil repellency can all be adjusted based on equipment and application needs.

Fast Response: Simply provide your equipment drawings or operational pain points, and our technical team will quickly produce samples and move to mass production.
