Iwata Moisture Filter with Pressure Regulator and Gauge is essential for optimizing the performance of both compressor and airbrush. The moisture filter uses a deflector plate to create a swirling air flow through a 5 micron element to ensure maximum water and dirt separation. The attached regulator features an adjustable locking knob and the gauge has a reading from 0-100 psi. This accessory can be attached either directly to the air source or inline between hoses. Includes thread sealant tape and adaptors. The Iwata Moisture Filter with Pressure Regulator and Gauge may be used with the Iwata Universal Spray Out Pot (CL300) and Iwata Universal Airbrush Holder (AH400) to complete the Iwata Workstation.
