Positive-Negative Pressure Union Filter

With the same convenience as the conventional vacuum filters (VFU series), the filter can be used in the positive pressure as well.

• Keeping the same usability with vacuum filter gVFU Series and usable with positive pressure
• Suitable as pre-filter in positive pressure system
• Element can be replaced without any tool, easy maintenance
• Positive-Negative Pressure Union Filter of Copper alloy free specification is available for the field requiring "No copper alloy" and "Low level ozone resistance"
