Frequently Asked Questions (FAQ)
-
What is the maximum operating temperature of this filter bag?
The bag is rated for continuous use up to 90°C (194°F). For short-term spikes, it can withstand slightly higher temperatures, but we recommend staying within the limit for optimal performance. -
Is this filter bag suitable for food-grade applications?
PTFE is an FDA-approved material for food contact. However, please confirm with your local regulations. We can provide material certificates upon request. -
Can I wash and reuse this bag?
Yes, the PTFE needle felt can be cleaned by backwashing, rinsing, or gentle washing. But repeated washing may reduce filtration efficiency over time. Replacement intervals depend on the application. -
What is the standard size range?
We offer standard sizes from 4x12 to 7x32 inches. Custom lengths and diameters are available – please provide your housing dimensions for a perfect fit. -
Does this bag have a metal ring or grommet?
Standard bags include a plastic or stainless steel ring at the top for sealing. You can choose the type that matches your housing. -
How does the 0.5 micron rating compare to other filter bags?
0.5 micron is a fine filtration level, suitable for removing particles like bacteria, fine powders, and precipitated solids. It is finer than standard 1-micron or 5-micron bags. -
What is the typical pressure drop across the bag?
Initial pressure drop is low (around 0.1-0.3 bar at 10 m³/h flow rate), and it increases as the bag loads. PTFE’s low friction helps maintain a lower pressure drop compared to other materials. -
Do you offer samples for testing?
Yes, we can provide small sample bags for evaluation. Please contact us with your requirements.
