TYPE 380/390 Series
Large Flow Capacity Stainless Steel
Air Filter Regulator & Regulator
INTRODUCTION
The Type-380/390 Large Flow Capacity Stainless Steel Filter Regulator & Regulator Series are designed for air or gas service. Maximum
allowable inlet pressure is 290 psi (20 BAR). Operating temperatures are -40
°
to 200
°
F (-40
°
to +93
°
C). The Type-380/390 is able to deliver up
to 425 scfm (12,000 nL/min) for rapid actuator stroking. To avoid exceeding outlet pressure limits in service, a pressure-relieving or pressure-
limiting device should be provided.

INSTALLATION
1. Install the regulator/filter as close as possible to the instrument or tool it is to service.
2. Clean all pipelines to remove dirt and scale prior to installation.
3. Install the regulator/filter so that the direction of flow is from the “IN” to “OUT” connection as marked on the body of the regulator/filter.
4. For best drainage, orient the drain valve so that it is at the lowest point on the drip well housing.
5. The exhaust port should be kept free and unplugged. Rotating the bonnet relative to the body may change the vent hole orientation.
6. Exhaust may be remotely vented by installing tubing to the 1/8” NPT port. Apply pipe compound or sealing tape to the mail pipe
threads prior to installing regulator/filter. Use caution to prevent the sealant from getting inside the regulator/filter.
WARNING:
Only qualified personnel should install or service a regulator. Regulators should be installed, operated, and maintained in
accordance with international and applicable codes and regulations, and ControlAir instructions. If the regulator vents fluid or a leak
develops in the system, it indicates that service is required. Failure to take the regulator out of service immediately may create a
hazardous condition. Personal injury, equipment damage, or leakage due to escaping fluid or bursting of pressure-containing parts may
result if this regulator is over pressured or is installed where service conditions could exceed the limits given in the Specifications section,
or where conditions exceed any rating of the adjacent piping or piping connections. To avoid such injury or damage, provide pressure-
relieving or pressure-limiting devices (as required by the appropriate code, regulation, or standard) to prevent service conditions from
exceeding limits. Additionally, physical damage to the regulator could result in personal injury and property damage due to escaping fluid.
To avoid such injury and damage, install the regulator in a safe location. The internal relief valve in the Type-380 regulators does not
provide full overpressure protection. The internal relief valve is designed for minor seat leakage only.
