Frequently Asked Questions
1. What is the difference between a wedge wire filter and a standard mesh filter?
Wedge wire filters (Johnson screens) use a continuous V-shaped wire profile, providing a larger open area and a self-cleaning surface. They are more resistant to clogging and can withstand higher pressure than traditional mesh filters. The slot size is consistent, offering precise filtration.
2. How does the automatic backwash work?
The filter is equipped with a pressure differential sensor or timer. When the pressure drop across the filter reaches a preset level (or at a set interval), the backwash valve opens, allowing reverse flow to clean the screen. The process takes only seconds and does not require stopping the main flow.
3. What materials are used for the filter element?
The filter element is made of stainless steel wedge wire, typically 304 or 316L. 316L is recommended for corrosive environments or high chloride content. The housing and fittings are also stainless steel to ensure complete corrosion resistance.
4. Can the control box be customized for different voltages?
Yes, the control box is available for 220V/50Hz as standard, but we can customize the voltage (e.g., 110V, 380V, 460V) and frequency (60Hz) upon request. Please specify your requirements when ordering.
5. What is the temperature range for this filter?
The standard filter can operate at temperatures up to 80°C (176°F) for continuous use. For higher temperature applications, we can provide seals and materials suitable up to 200°C. Please consult our technical team.
6. How do I choose the right filtration precision?
The filtration precision depends on the particle size you need to remove. Common slot sizes range from 100 microns (fine) to 2000 microns (coarse). We recommend analyzing your fluid’s particle size distribution; our engineers can help you select the optimal slot size.
7. What maintenance is required?
The automated backwash reduces manual cleaning. Periodic inspection of the control box, seals, and pressure differential is recommended. The wedge wire screen is durable and rarely needs replacement unless damaged by debris. Annual service intervals are typical.
8. Do you provide installation support or manuals?
Yes, we provide a detailed user manual with installation, operation, and troubleshooting instructions. Our technical support team is available via email or phone to assist with any questions. We can also offer on-site guidance for large projects upon request.
