Pressure Regulators
Model 8601
Description
Brooks® 8601 Pressure Regulators are high precision
supply pressure regulators which are direct-acting,
non-relieving units that provide bubble-tight shut-off on
helium at 100 psi.
Compact and economical, these units are assembled in
a “clean room” environment and are tested under
simulated operating conditions.
Design Features
• Compact design
• Suitable for line or panel mounting
• Pressure gauge connection
• Bubble-tight shut-off to 100 psi
• Replaceable stainless steel inlet filter element
• UL listed (Aluminum body only) as compressed gas
regulator for use with the following gases: air, argon,
helium, hydrogen, krypton, neon, nitrogen, oxygen or
xenon.
Specifications
Capacity
The pressure regulator is ideal for use at flow up to a
maximum of 1,000 sccm air.
Ratings
Maximum Inlet Supply Pressure - 250 psi (1,724 kPa)
Maximum Working Temperature - Standard: 140°F
(60°C), Optional - 350°F (177°C)
Typical Characteristics
(Helium 60 psig supply, 50 psig output)
Drift - Less than 1% in first fifteen minutes to total of no
more than 1.5% long term
Supply Pressure Effect - 10 psi increase in supply will not
change output more than 0.07 psi.
Flow Regulation - From 3 sccm to 70 sccm helium, output
pressure will not decrease more than 0.08 psig (0-10,
0-30 psi Regulators), 0.10 psig (0-60 psi Regulators),
0.125 psig (0-100 psi Regulators), 0.15 psig (0-150 psi
Regulators), 0.175 psig (0-200 psi Regulators)
Ambient Temperature Effect - Standard 60 psi range,
0.020 psi/°F.
Base Line Oscillation - .0025 psi
