Frequently Asked Questions
Q1: Why is “silicone-free” sealant crucial for pharmaceutical drying tunnels?
Standard silicone can outgas at high temperatures, causing chemical contamination. Our silicone-free heat-resistant sealant ensures zero contamination, which is vital for depyrogenation tunnels.
Q2: Can the filter survive being heated and cooled every day?
Yes. It is designed for heat cycle resilience, meaning the media and frame are engineered to expand and contract without cracking or losing seal integrity.
Q3: Is this filter compliant with food hygiene standards for roasting equipment?
Absolutely. All materials used in our heat resistant medium filter are selected for high thermal safety and low outgassing, ensuring contact air meets strict hygiene standards.
Q4: How does the “terminal filtration” design differ from general filters?
Our terminal filtration excellence focus ensures that this is the final, most reliable barrier for particulates before air enters the sterile zone of an industrial oven.
Q5: What is the benefit of the temperature-stabilized fiberglass media?
The temperature-stabilized fiber glass paper prevents the media from becoming brittle or shedding fibers during the intense heat of depyrogenation or roasting processes.
