7. FAQ: Professional Gas & Air Filter Technical FAQ
Q1: What are the mainstream materials for advanced gas filter elements?
Sintered PE, PTFE, stainless steel (316L), and specialty polymers. PE filters balance fine porosity and corrosion resistance for cost-critical use.
Q2: Which pore size (micron rating) suits medical oxygen filtration?
Typically 0.2–1.0 μm; ensures removal of bacteria/particles while maintaining low pressure drop. Oxygen Diffuser Filter series are configurable across this range.
Q3: Are your filters compatible with ANSI and ISO dimensions?
Yes, all main product lines conform to ANSI, ISO, GB/T, and can be adaptation-fitted to major brands (Pall, Parker, etc.).
Q4: What is the installation standard/guideline for PE filter units?
Follow manufacturer’s torque and sealing specs (ISO 2942). Use FDA/FKM seals for critical applications. Pre-flushing recommended before initial use.
Q5: How does operating pressure affect filter performance?
All filters are rated for specified MPa/bar. Over-pressurizing may cause pore deformation—always deploy filters within the tested safe range, as per data sheet.
Q6: What kinds of surface treatments are available?
Hydrophilic/hydrophobic treatments, anti-fouling coatings, and UV sterilization—specific to application requirements.
Q7: Is onsite performance testing offered?
Yes, our technical teams provide in-field validation: flow curve, particle challenge, and integrity testing using calibrated meters according to ISO standards.
