Frequently Asked Questions
-
Q: What is the difference between a Johnson filter and a traditional wire mesh screen?
A: Johnson filters use continuous v-shaped wedge wire wound around support rods, creating a smooth inner surface and precise slot openings. This design resists clogging, provides higher strength, and allows easy backwashing compared to woven mesh screens. -
Q: Can this filter be used for oil and gas applications?
A: Yes, the 316L stainless steel material offers excellent corrosion resistance against sour gas, brine, and hydrocarbons. The 300 PSI rating makes it suitable for many downhole and surface filtration applications in oil & gas. -
Q: Is the 0.3mm slot available for other pressure ratings?
A: We can customize the pressure rating by adjusting the wire thickness and support rod spacing. Pressure ratings up to 600 PSI or higher are available upon request. -
Q: How do I clean the filter?
A: The continuous slot design allows easy backwashing or chemical cleaning. For most applications, flushing with clean water at low pressure is sufficient. For stubborn deposits, ultrasonic cleaning or acid wash can be used. -
Q: What are the available end connections?
A: We offer flanged (ANSI, DIN, JIS), threaded (NPT, BSP), and plain end connections. Couplings and adapters can also be customized to match your piping system. -
Q: Do you provide samples before bulk order?
A: Yes, we can produce sample units for testing. Sample cost is chargeable but refundable upon large quantity orders. Please contact our sales team for details. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ for standard sizes is typically 10 pieces. For custom dimensions, please discuss with our engineers to determine feasibility. -
Q: How long is the warranty period?
A: We offer a 12-month warranty against manufacturing defects under normal operating conditions. Extended warranty options are available upon request.
