Oil Mist Filter Buying Guide for E2M1.5 Pumps

Compatibility

• Verify the filter is compatible with your specific Edwards pump model (e.g., E2M0.7, E2M1, E2M1.5, E2M2).
• Confirm the filter's suitability for your application's vacuum level requirements.
• Check if the filter is designed for your specific pump series (e.g., Speedivac 2).

Port Size and Connections

• Identify the required port size (e.g., KF10, KF25, NW10, NW25) for your vacuum system.
• Ensure the filter includes necessary adapters (e.g., NW10 to 3/4 BSP) for your setup.
• Check the compatibility of inlet and exhaust flanges with your existing connections.

Filter Element and Efficiency

• Consider the filter element material (e.g., epoxy-impregnated glass fiber).
• Look for filters with high DOP test efficiency (e.g., 99.999%).
• Determine if the filter is azide proof for your application.

Features and Monitoring

• Check for features like pressure relief valves for blocked elements.
• Look for semi-transparent bodies to monitor oil levels easily.
• Consider filters that offer protection from oil mist emissions.

Material and Dimensions

• Consider the material of the filter body (e.g., durable plastic).
• Verify the dimensions (height and width) to ensure it fits in your space.
• Check the weight of the filter for ease of installation and maintenance.

Additional Considerations

• Explore oil return kits for maintaining optimal pump performance.
• Ensure the product meets relevant health and safety regulations (e.g., COSHH).
• Consider the availability of replacement filter elements.
