Frequently Asked Questions
Q1: What is the maximum operating temperature for this filter series?
Our Thermo-Guard series is engineered for continuous performance in environments ranging from 150°C to 300°C, ensuring safe operation in high-heat industrial zones.
Q2: Why are aluminum foil separators used in heat resistant filters?
The corrugated aluminum foil separators provide superior structural stability, maintaining perfect pleat spacing and preventing media collapse during rapid heat cycles.
Q3: Is this filter suitable for pharmaceutical depyrogenation tunnels?
Yes. With silicone-free heat-resistant sealant and high-efficiency glass fiber paper, it meets the strict purity standards required for pharmaceutical sterilization.
Q4: How does low initial resistance benefit my industrial oven operation?
Our low initial resistance (≤150-250Pa) reduces the load on your ventilation fans, significantly lowering energy consumption while maintaining high-volume airflow.
Q5: Will the frame warp during frequent heating and cooling phases?
No. We use high-grade galvanized or stainless steel frames designed for maximum structural integrity, ensuring the filter remains rigid even during repeated thermal expansion.
