China Cartouches Filtrantes Plissées pour Collecteur de Poussière – Factory Overview

These pleated filter cartridges are engineered for high‑efficiency dust collection in industrial ventilation systems. The geometric pleat pattern increases surface area while maintaining low pressure drop, enabling continuous operation at elevated airflow rates. Manufactured in China under strict process controls, they meet the performance demands of metalworking, woodworking, and chemical processing facilities.

Technical Characteristics

Filter media consists of a synthetic polyester blend with a graded fiber density that captures particles down to 1 µm at 99.9 % efficiency. The pleated geometry provides a nominal filtration area of 2.5 m² per cartridge, reducing the number of units required for a given collector size.

Materials and Construction

The media is bonded to a corrosion‑resistant steel support cage using a high‑temperature adhesive that maintains integrity up to 120 °C. End caps are fabricated from galvanized steel with a rolled flange to ensure a tight seal against the housing gasket. All seams are ultrasonically welded to prevent fiber shedding under pulse‑cleaning cycles.

Design Features

• Optimized pleat height of 20 mm balances surface area and structural rigidity.
• Anti‑static treatment applied to the media reduces dust re‑entrainment during cleaning.
• Standard outer diameter of 140 mm fits common collector housings without adapters.
• Optional PTFE coating available for enhanced chemical resistance in aggressive environments.

Applications

In metalworking shops, the cartridges capture fine metal oxides and grinding swarf that would otherwise accumulate on downstream fans and cause imbalance. Woodworking facilities benefit from the high dust‑holding capacity, which extends service intervals between pulse‑cleaning cycles and reduces maintenance downtime. Chemical processing plants rely on the media’s resistance to mild acids and solvents, preventing premature degradation when filtering volatile organic compounds. The low pressure drop design ensures that energy consumption of the extraction fan remains stable even as the filter loads. Collectively, these characteristics support continuous operation while protecting worker health and equipment longevity.

Quality Control

Each batch undergoes dimensional verification of pleat height, media thickness, and end‑cap squareness using calibrated laser gauges. Filtration efficiency is tested on a standardized test rig with ISO‑12103‑1 A2 dust to confirm performance before shipment. Visual inspection checks for media tears, adhesive uniformity, and proper sealing of the end caps.

Customization Options

• Alternative media materials such as cellulose‑synthetic blend or PTFE‑coated polyester.
• Varied lengths from 300 mm to 1200 mm to match specific housing depths.
• Different end‑cap materials including stainless steel 304 for corrosive atmospheres.
• Custom pleat geometry (e.g., V‑pleat or rounded pleat) to optimize pressure drop for high‑flow applications.

Frequently Asked Questions

Can the cartridge dimensions be customized?

Yes. Length, outer diameter, and pleat height can be adjusted according to the collector housing specifications. Detailed drawings are required before quotation.

What information is needed to obtain a quote?

Required data includes the target airflow rate, maximum dust concentration, operating temperature, and any chemical exposure details. Housing dimensions and preferred end‑cap material are also helpful.

Which materials are available for the filter media?

Standard offering is a polyester‑based synthetic blend. Options include cellulose‑synthetic blend, PTFE‑coated polyester, and anti‑static treated variants, all subject to minimum order quantities.

How is quality inspected before shipping?

Every cartridge is checked for dimensional accuracy, media integrity, and sealing quality. A representative sample from each lot is subjected to a filtration efficiency test per ISO 15012‑1 to verify performance.
