EFC™
ELECTRONIC FLOW CONTROL FOR COMPRESSED AIR
INSTALLATION AND MAINTENANCE
THE EFC SHOULD NOT BE USED IN AN EXPLOSIVE OR FLAMMABLE AREA. PROTECTION PROVIDED BY
THE EQUIPMENT MAY BE IMPAIRED IF USED WITH ACCESSORIES NOT PROVIDED OR RECOMMENDED
BY EXAIR, OR IS USED IN A MANNER NOT SPECIFIED BY EXAIR CORPORATION.
EXAIR’s EFC is an electronic flow control for compressed air that provides precise “on/off” timing control of the compressed air
supplied to the EXAIR products. The EFC permits the critical timing adjustment needed to operate the EXAIR products as
efficiently as possible, turning on the compressed air only when it is needed. This control system provides flexibility by sensing
distance as well as providing numerous valve operating modes and timing delays. The EFC is applicable to many different
manufacturing lines and environments. The sensor is compact which makes it simple to install in tight spaces. The polycarbonate
enclosure of the EFC control is NEMA 4/IP56 rated which is ideal for wet locations.
INSTALLATION
1.
Install EXAIR’s engineered airflow product(s) such as the Super Air Knife, Air Amplifier, Air Nozzles, etc., following the
“Installation and Maintenance Sheet” that was included with that product.
2.
Connect the compressed air supply to the EFC solenoid valve, paying attention to the flow direction arrow on the brass valve
body (in and out). The solenoid valve should be located downstream from a filter and before the compressed air product. For
ease of connecting the solenoid valve to the compressed air pipe, the electrical coil can be detached from the valve body by
using a flat blade screwdriver to remove the metal clip that holds the coil to the valve body. Connect the compressed air line to
the EXAIR product(s) and re-install the electrical coil, securing it to the valve using the clip.
3.
Prior to the electrical hook up, install the EFC timer control in a location that is convenient for adjustment of the timer settings.
Do not permanently wire the EFC. Do not position the EFC in a space where it is difficult to disconnect the power cord. It
should not be mounted in direct sunlight. Always consider the best location that is convenient for the installation of piping air
to the EXAIR product as well as connecting the unit to a power source. To access the mounting holes of the EFC timer control
box, remove the cover by turning the four screws counter-clockwise. The mounting holes are the same as those used for the
cover screws. It is recommended that all four holes be used (if possible) for a secure mounting that will minimize breakage.
Four mounting tabs which attach to the back of the enclosure with screws can also be used.
