Description
Overview
The I/PAC Integrated Process Air Control package combines a field-mounted I/P transducer, Type 330 filter regulator, pressure gauge, and mounting hardware into a preassembled solution for process control applications. Designed to simplify installation and replacement, the I/PAC is available with either the Type 950XP or Type 595XP I/P transducer and provides a compact, field-rugged airset assembly.
The package can mount directly to a 2″ pipe, valve yoke, or other equipment using 2.25″ bolt spacing. Integrated units retain the applicable hazardous-area approvals of the selected I/P configuration, including FM, CSA, and ATEX certifications.
By combining signal conversion, air filtration and regulation, pressure indication, and mounting hardware into one assembly, the I/PAC reduces field assembly requirements and provides a convenient replacement or upgrade option for automated valve and process control systems.

How to Select the Right Configuration
Selecting the correct I/PAC configuration depends on the required I/P transducer performance, pneumatic output range, hazardous-area approval, filtration requirement, exhaust configuration, and mounting arrangement.
- Select the Type 950XP / Type 330 combination when higher flow capacity and higher precision are required
- Select the Type 595XP / Type 330 combination when compact size and extended low-temperature capability are priorities
- Select the 3-15 psig output range for standard pneumatic control valve and actuator applications
- Select the 3-27 psig or 6-30 psig output range when higher pneumatic output pressure is required
- Select the Field Selectable Outputs option on applicable Type 950XP configurations when field-adjustable output ranges are required
- Select the Tapped Exhaust option when exhaust air must be captured or routed away from the assembly
- Select the 5 Micron Filter option when finer particulate filtration is required
- Select the ATEX option for installations requiring the corresponding ATEX hazardous-area certification
- Use direct mounting where the assembly can attach directly to the controlled equipment
- Use the bracket arrangement for 2″ pipe mounting, valve-yoke mounting, or offset pipe mounting
