2
Proper Installation
Handle the cage with care to avoid damage. Install it inside the filter bag according to the manufacturer's instructions, ensuring a proper fit and alignment.
3
System Startup
Gradually start the filtration system and monitor the pressure differentials. Adjust the airflow and operating parameters as needed to ensure stable operation.
4
Regular Maintenance
Regularly inspect the cage for signs of wear, corrosion, or damage. Replace the cage if necessary to maintain optimal filtration performance.
Operation Checklist
Verify cage dimensions and specifications
Ensure proper installation and alignment
Monitor and record pressure differentials
Follow manufacturer's maintenance recommendations
Safety Regulations
Temperature Hazard
Avoid exposing the Envelope Type Filter Bag Cage to temperatures exceeding its maximum rating of 250°C. Ensure proper ventilation and cooling systems are in place to maintain safe operating temperatures.
Handling Precautions
Wear appropriate protective clothing, gloves, and safety glasses when handling the cage. Avoid contact with sharp edges or protruding wires.
Chemical Exposure
While the cage has an anti-corrosion coating, prolonged exposure to certain chemicals may degrade its performance. Refer to chemical compatibility charts for specific applications.

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.
