Q1: What is the filtration precision of the RFL series?
A: The RFL series offers multiple filtration grades, ranging from 0.01 μm to 1 μm, with oil removal efficiency as high as 99.99%.
Q2: Can this filter be used for gases other than compressed air?
A: Yes, the stainless steel construction makes it suitable for various industrial gases, including nitrogen, argon, and natural gas. Please consult us for compatibility with specific gases.
Q3: How often should the filter element be replaced?
A: Replacement intervals depend on operating conditions and air quality. Typically, elements are replaced every 6–12 months or when pressure drop exceeds acceptable levels.
Q4: Is the filter housing corrosion-resistant?
A: Yes, the RFL series is made from high-grade stainless steel (304 or 316), offering excellent resistance to corrosion, moisture, and chemicals.
Q5: Can the filter be cleaned and reused?
A: The filter housing is reusable; only the internal filter element needs periodic replacement. This reduces long-term operating costs.
Q6: What industries commonly use the RFL series filter?
A: It is widely used in food and beverage, pharmaceutical, electronics, chemical, automotive, and laboratory applications where clean, oil-free, and dry compressed air is critical.
