Operation Guide
1
Pre-installation Inspection
Inspect the filter bag for any damage to the membrane or fabric. Ensure the bag dimensions match your filter housing specifications. Check the sealing surface for any defects that could cause leaks.
2
Proper Installation
Gently insert the filter bag into the cage, ensuring the membrane surface is not scratched or damaged. Secure the bag to the tube sheet according to manufacturer instructions, ensuring a tight seal. Avoid over-tightening, which may damage the bag.
3
System Startup
Gradually increase the system airflow to allow the bag to seat properly. Monitor differential pressure readings to ensure normal operation. Avoid sudden pressure surges, which may damage the membrane layer.
4
Regular Maintenance
Perform routine visual inspections for signs of wear, damage, or clogging. Clean or replace bags as needed to maintain filtration efficiency. Adjust cleaning cycles based on operating conditions to optimize performance.
Operation Checklist
Verify bag dimensions and compatibility
Ensure membrane surface is intact
Monitor differential pressure regularly
Inspect for signs of wear or damage
Safety Regulations
Temperature Caution
Avoid exposing the filter bag to temperatures exceeding 150°C, as this may damage the membrane layer. Prolonged exposure to temperatures above 130°C may reduce service life and filtration efficiency.
Handling Precautions
Wear gloves and protective clothing when handling filter bags to prevent damage to the membrane. Store bags in a dry, clean environment away from direct sunlight and chemicals. Avoid sharp objects that could puncture or tear the fabric.
Chemical Exposure
While polyester is resistant to many chemicals, avoid prolonged exposure to strong acids or alkalis. In chemically aggressive environments, consult with our technical team for suitable material recommendations.

High dust load & continuous production (e.g., sintering workshop in steel mills)
Choose high - dust - holding filter bags + strong - load cage frames → Reduce bag - changing frequency (cut labor and shutdown losses), stably support production line operation.
Space - constrained & fine dust (e.g., electronics factory grinding workshop)
Choose pleated cartridges + custom brackets → Achieve high - efficiency filtration (precision ≤1μm) in limited space, suitable for low - air - volume, high - precision needs.

FAQs
Can I test Mingkai's filter bags before purchasing?
Yes. We offer free sample testing for filter bags. You can evaluate filtration efficiency, material durability, and compatibility with your dust - laden airflow in your actual working conditions.
Can Mingkai customize the dimensions of dust bag cages?
Absolutely. Our bag cages support custom - made lengths, diameters, and ring spacings. Just provide your filter housing specs or application requirements, and we’ll tailor the structure for a perfect fit.
Can dust filter cartridges replace filter bags in my existing system?
It depends on your equipment design. If space and airflow allow, we can conduct a free on - site assessment. For systems with limited vertical space, cartridges (with compact structure) are often a viable upgrade option.
What’s the maximum temperature Mingkai's filter bags can withstand?
It varies by material. For example: PTFE bags handle up to 260℃ continuously; Aramid (Nomex®) resists 220℃; For extreme 280℃+ scenarios, we recommend FMS composite materials.
How long does the anti - corrosion coating on dust bag cages last?
Our standard galvanized cages last 3–5 years in general industrial environments. For harsh corrosive conditions (e.g., chemical plants), we offer epoxy - coated or stainless - steel options, extending service life to 8–10 years.
