Frequently Asked Questions
What determines the service life of filter bags?
Filter bag life primarily depends on operating conditions and maintenance practices. Under standard conditions, our bags typically last 12-24 months. Key factors affecting lifespan include operating temperature, chemical exposure, maintenance frequency, and particle load characteristics. Regular monitoring of differential pressure and proper maintenance can significantly extend service life.
How do I select the right filter bag for my application?
Selection should be based on your specific process requirements. We evaluate five critical factors: operating temperature, chemical compatibility, particle size distribution, air-to-cloth ratio, and system pressure limitations. Our technical team can help analyze these parameters to recommend the optimal solution for your operation.

Our technical team can help analyze these parameters to recommend the optimal solution for your operation.
What maintenance is required for optimal performance?
Effective maintenance includes regular differential pressure monitoring, scheduled cleaning cycles, and periodic visual inspections. We recommend maintaining a performance log to track key metrics and optimize cleaning intervals. This proactive approach helps prevent unexpected downtime and extends filter life.
When should I replace my filter bags?
Key replacement indicators include:
- Sustained high differential pressure that doesn't reduce after cleaning
- Visible damage or wear during inspection
- Decreased collection efficiency
- Exceeded recommended service hours
- Failed integrity tests
Early detection of these signs helps prevent system inefficiencies and product loss.
What's the proper installation procedure?
Proper installation is crucial for optimal performance. This includes:
- Ensuring correct cage fitment
- Proper tensioning of the bag
- Secure sealing at all connection points
- Verification of proper alignment
Our installation guide provides detailed steps, and technical support is available if needed.
How do temperature fluctuations affect performance?
Temperature variations can significantly impact filter performance. Our bags are designed to maintain structural integrity and filtration efficiency within their specified temperature range. The PTFE construction ensures consistent performance even with temperature fluctuations up to 260°C without compromising chemical resistance or filtration efficiency.
What cleaning methods do you recommend?
We endorse several cleaning methods based on your specific application:
- Pulse-jet cleaning for continuous operation
