Filter element product structure

This product is engineered for durability and high filtration performance. The end cap is made of high-strength black plastic, offering lightweight corrosion resistance, while the internal framework features a galvanized diamond mesh that ensures structural stability and impact resistance. The core filter layer consists of high-quality polyester fabric, providing excellent dust-holding capacity and optimal airflow. Sealing is achieved with a nitrile rubber gasket, which resists oil and aging to effectively prevent leakage. For installation, the three-lug chuck connection enables quick, secure pipe attachment, ensuring reliable sealing and easy maintenance—making it ideal for demanding industrial applications.

Aspect	Three‑Lug Cartridge	Standard (Plain) Cartridge	Flanged Cartridge	Clamp‑Type (Bayonet) Cartridge
Core Design	Upper end cap with three radial lugs (ears)	No special mounting feature; simple cylindrical design	The upper end cap is a flange ring, usually larger than the cartridge body	Connected via clamps or bayonet‑type locking rings
Mounting Method	Twist‑and‑lock quick installation; no support rod needed	Various methods, often more complex	Secured with studs and nuts	Quick‑connect via clamps; can be vertical or side‑mounted
Ease of Removal	Fast and convenient (quick‑release design)	Relatively cumbersome	Requires loosening nuts – more steps	Quick – similar to three‑lug in speed
Size Flexibility	Highly flexible – outer diameter and height are largely unrestricted	More constrained	Customisable, but limited by flange standards	Limited by clamp/bayonet specifications
Cost	Saves on support rods and mounting hardware – lower installation cost; may require one extra adjustment step compared to some quick‑release types	Initial purchase cost may be lower	Additional cost for the flange and hardware	Additional cost for clamps/bayonet rings
Performance	High filtration efficiency (up to 99.99%), low pressure drop, good pulse‑cleaning performance	Performance depends on material and design	Excellent sealing; suitable for high‑dust‑load conditions	Good sealing, reliable and fast to change
Typical Applications	General industrial dust collection, especially where rapid maintenance is required	General industry, automotive, etc.	Wet, oily, or high‑dust‑concentration environments	Construction machinery, mixing plants, etc.

1. Choose a three‑lug cartridge when you prioritise easy installation/maintenance and large size flexibility.
2. Choose a flanged cartridge if your equipment uses flange connections or operates in wet/oily/high‑dust conditions.
3. Choose a clamp‑type cartridge if your equipment has clamp interfaces and you need the fastest possible changeover.

Working Principle

The primary function of a dust filter is to separate solid particles from a gas, and it does so through a combination of several physical mechanisms:

•Sieving (or Screening): This is the most basic principle, where filter media acts like a sieve, blocking and trapping any dust particle larger than the pores of the filter material.

•Inertial Impaction & Interception: As the air flows around the fibers of the filter media, larger or high-velocity dust particles cannot follow the airstream's path through the filter. Due to their inertia, they collide directly with a fiber and are trapped. Medium-sized particles may also be intercepted when they come into proximity with a fiber and stick to it.
•Diffusion: The smallest dust particles (typically sub-micron in size) are in constant, random motion (Brownian motion). This random movement increases the chance that they will come into contact with and be captured by the filter fibers. This principle is particularly effective for capturing the most harmful, ultra-fine particulates.
•Electrostatic Attraction: Many filter elements are designed with or have materials that create electrostatic charges. These static forces can attract oppositely charged dust particles, enhancing the capture of fine dust without hindering airflow.
