GENERAL SAFEtY INFORMAtION
Speedaire air pressure regulators features self-relieving and high
capacity. These heavy-duty units are designed for commercial/industrial
applications, providing high air flow and maintaining the set pressure
with minimum pressure drop between the actual air compressor outlet
pressure and the set pressure to tools and equipments.
The device may only be operated in the permanent installation in
pressured air systems. Improper use or modifications to the device or
the use of its components which are not tested and approved by the
manufacturer may result in unforeseen damage.
Air line regulators are used in a variety of air systems which may go
with air compressor, spray gun, filters, lubricators, hoses, etc. Read and
understand all safety instructions, installation instructions and operation
instructions before using this unit. Basic safety precautions should
always be followed to reduce the risk of personal injury and/or property
damage.
General Safety inStrUctionS
1. Read all safety instructions. Failure to do so may cause harm to you
and others.
2. Keep children and unauthorized persons away from the device.
Ensure that children are not able to play with the device.
3. Do not overload the device. Do not use the device for purposes for
which it is not intended.
4. Always make sure that the air line is in good condition.
5. Hose and connection should be inspected to avoid any leakage
before use.
6. Residual air in the system needs to be released before service or
repair.
7. Ensure that all connections and supply lines are rated for the required
pressure and air flows.
CAUtION
Polycarbonate bowls are not recommended for
use in atmospheres containing chemicals such
as acetone, benzene, carbon tetrachloride, gasoline, toluene and/or air
compressor systems using synthetic fire-resistant lubricants.

INStALLAtION INStRUCtIONS
1. Before installation, check whether the connections used match the maximum
pressure of the regulator.
2. Shut off air pressure from air system. Install the regulator vertically or at any angle
in the air line. Ensure that the regulator is installed with inlet/outlet air flow in the
proper direction of arrow on the unit. The regulator should be installed upstream of
lubricator(s), and cycling valve(s) in the air line, and should be as close as possible to
the device being serviced.
note: Model 4ZM05 and 4ZM06 have the word IN stamped next to the air inlet port.
3. Connect pipes to the inlet and outlet ports using pipe thread sealant tape on male
threads only. When screwing pipes together, prevent ingress of shavings and sealant
to the interior of the unit. Contaminations in the unit may cause it to fail.
4. Make sure that all connections to the regulator are tight and secure.
5. Install a pressure gauge to either of the gauge ports facing the operator. The other
gauge port should be plugged or can be used as an additional air outlet for regulated
air.
