New Air Filter Regulator Meets NACE Requirements for Corrosive Environments 2018-10-16

ControlAir Inc. is pleased to announce the introduction of the Type-335 NACE Filter Regulator. This unit incorporates all of the operating features of ControlAir’s Type-330 Filter Regulator, but is constructed of materials that meet NACE specification #MR-0175 for sulfide stress cracking.

Features:
 NACE COMPLIANT MATERIALS – all materials of construction meet NACE MR-0175 requirements for corrosive resistance
 INTEGRAL THROUGH-BOLT MOUNTING – to most popular industrial valves
 STABLE OUTPUT and REPEATABILITY – provides constant control under variable flow rates and supply pressures
 LOW AIR CONSUMPTION – decreases operating cost
 TAPPED EXHAUST – allows remote venting media
 1/4" NPT PORTING – 2 gauge ports
 COMBINATION OF ALUMINUM BODY and STAINLESS STEEL TRIM – offers lower cost alternative to all stainless steel
 VITON ELASTOMERS
The Type-335 NACE Filter Regulator is designed specifically for use in corrosive sour gas environments and provides instrument quality air to valves, pneumatic controllers, transmitters, transducers, valve positioners, air cylinders, and a wide range of pneumatic control systems. The Type-335 NACE is ideal for gas and oil field applications. Other applications include petrochemical processing, both on and offshore; food; pulp and paper; pharmaceutical processing; pollution control; wastewater treatment and research projects.

The Type-335 NACE Filter Regulator is available in 1/4” NPT porting. Output ranges include 0-30 psig (0-2 BAR), 0-60 psig (0-4 BAR) and 0-100 psig (0-7 BAR). Maximum supply pressure is 250 psig (17 BAR). Standard mounting allows for pipe or through body. Temperature limits range from -20º F to 180º F (-29º C to 82º C). Flow capacity is 20 scfm at 100 psig supply with 20 psig output. Exhaust capacity is 0.1 scfm (2.83 Nl/min) with downstream 5 psig (0.3 BAR) above set point. Air consumption is less than 5 scfh. Effect of Supply Variation is less than 0.25 psig (0.017 BAR) for 25 psig (1.7 BAR) change. The Type-335 NACE Filter Regulator weights 1.2 lb (.45 kg).

ControlAir Achieves Safety Integrity Level (SIL 3) Certification for Volume Boosters 2018-10-16

ControlAir, Inc., a leading manufacturer of precision pneumatic and electro-pneumatic controls, is pleased to announce that its Type-6500 Aluminum and Type-6600 Stainless Steel Large Flow Capacity Volume Boosters were awarded a Certificate of Compliance to IEC 61508 for a SIL 3 safety rating.
SIL is an industry measure of safety system performance and reliability, and is used as part of the Functional Safety Standard IEC 61508 to calculate risk protection in a system. When a company is using the IEC 61508 standard for safety, SIL components are required in system design.
The IEC 61508 standard defines the requirements to ensure products have a high level of resistance to random hardware and systematic design failures. ControlAir’s Type-6500/6600 Large Flow Capacity Volume Boosters were evaluated by a qualified third party certification agency, Factory Mutual (FM), which assessed and certified that the Type-6500/6600 Volume Boosters had been designed and developed in accordance with the IEC 61508 standard. FM followed a rigorous process that verified the Safety Integrity Level (SIL) for the Type-6500/6600 series hardware design, as well as its manufacturing and quality control procedures.
The Type-6500/6600 Large Flow Capacity Volume Boosters are ideal for any application that requires high flow capacity or remote pressure control. Typically they are used to increase throttling speed of large volume control valve actuators. When used in a safety system, the volume boosters are used in conjunction with a valve actuator, to perform a safety-related function. The greater air flow provided by the Type-6500/6600 units allows a valve to actuate more rapidly, which would then allow a safety shut-off system to reach a safe state quicker.
The Large Flow Boosters handle up to 250 psig (17.0 BAR) supply pressure and deliver an output pressure up to 150 psig (10.0 BAR). The units provide a flow capacity of up to 400 SCFM (11,320 Nl/min). Units are rated to a wide operating temperature range of -40º to 200ºF (-40º to 93ºC). Exhaust capacity is 100 scfm (2,830 Nl/min). The Type-6500/6600 are available in 3/4" and 1” NPT porting.
ControlAir Inc. manufactures precision pneumatic and electro-pneumatic controls. ControlAir’s markets include process control, semiconductor, printing and converting presses, diagnostic and surgical medical equipment, robotics, quality control, automotive, analyzers, compressors, pumps and paint equipment.
