Air filter cartridge with internal thread (dust collecting filter cartridge with internal thread)
The female thread filter cartridge is a dust collecting filter cartridge that is screw-mounted using a female threaded connection assembly. Most often used in vacuum loaders, pneumatic loaders, on-board dust collectors of drilling rigs and small-sized dust collection equipment operating under vacuum. Fastens directly by screwing onto the thread; differs from flanged chucks and six-lip snap-on chucks.
🧱 Analysis of the design
1.Connection unit with internal thread at the end. There is a metal internal thread built into one end of the chuck; The cartridge is screwed directly onto the fitting of the equipment with an external thread. There is a rubber sealing gasket; After tightening, a tight seal without air leaks is ensured. No flange bolts or six-arm latches are required - the mounting is threaded.
2. Internal and external metal protective mesh. The outer protective mesh protects the pleated filter material; The internal support mesh absorbs the vacuum and prevents the filter material from collapsing.
3.Pleat polyester filter material. The folded structure increases the filtration area; Available materials: regular polyester, PTFE-coated polyester, antistatic polyester.
4.Closed end cap at the other end. Flow direction: from outside to inside; dusty gas enters from the outside of the cartridge and, after cleaning, exits through a hole with an internal thread; Pulse backflushing is possible.
✨ Key product features
✅ Threaded fastening, easy installation and dismantling. Screwed on and removed without bolts or latches; Convenient replacement of the filter element in cramped equipment spaces.
✅ Stable sealing, suitable for working under vacuum. The thread presses against the sealing gasket; suitable for vacuum equipment; Prevents dust from leaking and protects the vacuum pump and fan.
✅ Wide selection of filter materials:
plain polyester: recovery of dry powders;
PTFE coated polyester: wet ultra-fine sticky dust, easier to clean;
antistatic design: for explosive environments in the production of lithium batteries and chemical powders.
✅ Compact sizes. Mainly cartridges of small and medium diameter, short length; Suitable for small-sized dust collection and suction equipment.
📌Areas of application
Vacuum loaders, pneumatic loaders for powders (most often used)
Onboard dust collectors for down-the-hole drilling rigs and drilling rigs
Small-sized dust collection under vacuum, recovery of exhaust air during pneumatic transport of powders
Powder recovery in the food, pharmaceutical and chemical industries
💡 Key points of operation
1.Installation: align with the male threaded fitting and tighten; ensure that the sealing gasket is in an even position without distortion.
2.Cleaning: Pulse backflushing is supported.
3. Temperature: for ordinary polyester during long-term use - no higher than 120 °C.
