MicroAir II
Tubing Extrusion Equipment – Air Pressure Regulation and Control:
The MicroAir II accepts Air Up and Air Down contact closure inputs from a O.D. Gauge made by LaserLinc, Zumbach or BetaLasermike, or other controllers (RDN) with up/down contact closures or logic outputs. Pressure is regulated by balancing against a low tension spring and by venting the surplus air.
Two front panel buttons for manual control and the externally controlled inputs for auto control adjust the pressure set point by means of a small motor which adjusts the spring tension. The buttons are dual-speed for slow or fast pressure changes. Indicators show Up, Down, and limit conditions. Zero to full Scale in approximately 2 minutes.
Air Input: The air inlet is connected to normal factory air which has been regulated down to approximately 50 psi.
Power: 110/220 VAC 50/60Hz
Dual selectable voltage input 110 or 220 volts
Range Available from 0-3” of water up to 0-5 psi. A range must be specified when ordering. Check out the Range Page.
Options:
- Digital LED pressure readout for more precision and easier reading. It has better than a 0.1 inch of water resolution. Ranges below 10″ of water can have two decimal places.
- OUTPUT Options for closed-loop control:
- Voltage Pressure output – can be 1-6, 0-5 or 0-10 VDC.
- Current output – 4-20 ma output
- Remote Control unit – A small (8” x 5” x 2”) ss box with standard 100 foot cable, with up/down control buttons and large digital display. Remote requires 4-20 ma output option in MicroAir II to connect.
- New Stand with rollers is available to purchase in the U.S.A.
- An External Air Pump is also available for use with ranges below 60″ of water.
- IMPROVEMENTS
-
Internal body improvements have been made to the MicroAir I for better precision and stability at the lower ranges. Our units might look the same on the outside but internally they have greatly been improved upon in the last few years.
-
Available in single, dual and 3-channel units for multilumen tubing. Check out MultiAir Page. All units are CE compliant.
Be sure to check out MicroAir Regulator page and Air Pressure Page for more information.
MicroAir II, Ultra Low Air Pressure Controller for precise control of tubing outside diameter by regulating air pressure to a set point.
