Type 300 Series

Instrument Air Filter and Filter Regulators

Type 300 Filter Regulator, Type 310 NACE compliant

Filter Regulator and Type 320 Filter

Series Features

• Corrosion-Resistant and

NACE Compliant Construction

Types 300 and 320 feature aluminum

die-castings, ﬁnished with irridite and

baked epoxy. Materials in the Type 310

meet NACE MR-01-75 requirements.

• Depth Filter

Units come equipped with hig

h capacity

40 micr

on depth ﬁlter housed in dripwell

• Two Outlet Connections

Provides piping versatility

Regulator Features

• Stable Output and Repeatability

Provides constant control under

variable ﬂow rates and supply

pressures

• Low Droop At High Flow Levels

Aspirator design helps maintain

set pressure at higher ﬂow levels

• Tight Shutoﬀ

A soft, rubberized valve provides a

positive shutoﬀ and compensates

for

dirt and other foreign matter

• Lo

w Air Consumption

Decreases operating cost

• Tapped Exhaust

Allows captured exhaust

Type 300 Filter Regulator

The Type 300 Instrument Air Filter Regulator is designed to

provide clean, accurate air pressure to instruments, valves,

and other automatic control equipment. This ﬁlter regulator

has been proven to provide accurate operating characteristics

under variable conditions. Durable materials and a standard

epoxy paint ﬁnish provide long lasting corr

osion resistance in

harsh industrial environments. The Type 300 is a quality unit

that is ideal as an economical alternative for control of

process applications.

Type 310 NACE Filter Regulator

This unit incorporates all of the operating features of the

Type 300 ﬁlter regulator, but is constructed of materials

that meet NACE speciﬁcation #MR-01-75 for sulﬁde

stress cracking. Designed speciﬁcally for cor

rosive sour

gas environments, the Type 310 NACE is ideal for oil ﬁeld

applications.

Type 320 Filter

The Type 320 Filter unit is a 40-micron depth ﬁlter that

removes dirt, moisture and other particles from air and

gas lines. Robustly constructed of die-cast aluminum

with a baked epoxy ﬁnish, this unit stands up in corrosive

operating conditions. This ﬁlter is an economical alternative

for air supply li

ne applications that don't require a pressure

reducing regulator.
