Series PRA/PRAM features two opposing large area frictionless rolling diaphragms. Process pressure is applied to one of the diaphragms; air pressure is applied to the other. Because the air pressure can be maintained with more accuracy than the force provided by a spring, the PRA/PRAM offers greater sensitivity and less variance from set pressure than any thermoplastic pressure regulator previously available. The PRA/PRAM can be used in combination with Plast-O-Matic’s patented Stabilizer which measures downstream liquid pressure and provides continuous feedback control for even greater sensitivity and performance. Molded and machined valves in 1/4″ through 3″ and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Set range 5-125 PSI. This is a Specialty Custom product; consult factory for availability. Minimum quantities may apply.

This process uses the impact velocity of the air oil mixture, along with centrifugal action - making the mixture very lean.

Series PRD/PRDM is a differential pressure regulator with a port for a downstream pressure sensing line. The sensing line feeds the pressure downstream of the equipment being protected to the top of the spring housing, which assists the spring in keeping the regulator open against the pressure directly at the regulator outlet. When pressure downstream begins to drop (as it would when a filter becomes more and more clogged), the regulator begins to close and becomes fully closed when the differential setting is reached. This assures against overpressure across the equipment. Molded and machined valves in 1/4″ through 3″ and metric pipe sizes in popular thermoplastic materials with a wide range of connection types. Differential set range 5-50 PSI.

Air Oil Separation Process:  After the air is being compressed in an oil flooded compressor, the air oil mixture enters with high velocity into the Air Oil Separator tank. Here it undergoes a unique and efficient 3 stage separation process which removes the maximum oil content.   This process uses the impact velocity of the air oil mixture, along with centrifugal action - making the mixture very lean.   The final stage of this separation consists of passing the lean mixture through the Air Oil Separator.   What is an Air Oil Separator?  An Air Oil Separator is a filter which separates the oil from compressed air. Thus leaving the compressed air with an oil content of < 1 ppm.  Air Oil Separation done by a coalescent media (separator element)    Importance of Air Oil Separator:    An Air Oil Separator plays a key role in the separation process. It ensures that only the air and no oil is delivered to the outlet. Hence it is important that the separator should be replaced from time to time. Care should be taken that an authentic separator needs is used.   Following is the significance of on time replacement and use of genuine separators.    Importance of On Time Replacement:  Pressure drops across the separator:  Pressure drop increases due to prolonged use and use of poor-quality separator. The pressure difference across the separator element directly converts to power cost.  Additional cost and change in system:  The compressor capacity decreases due to flow restriction by clogged separator element. It can even reach a point of 12% in extreme conditions.  The compression ratio of 7 bar machine increases to 9.64 (extreme condition). At this ratio, the load on bearings will be quite high! .  A 30-kW compressor will cause you an additional power cost of INR Rs.5000, due to separator replacement delay by just 10 days of continuous operation. Timely replacement can avoid this unnecessary expense.    Importance of using genuine Air Oil Separator:    Safety hazard:  Usage of inferior quality parts will result in serious damage, including the possibility of a fire accident.  Inadequate earthing can cause a separator to collapse (25% risk). It may causes fire and may also destroy the entire machine.  Reduced machine performance:  Spurious separator leads to additional resistance for air flow. It creates more pressure drop and thus puts additional load on the motor. Inadequate separation deteriorates air quality, reduces performance, and damages the downstream components.  High power consumption:  Due to  dense in filtration media, additional pressure drop is created.    This causes additional power consumption. Every 1 bar (14.5 Psi) of pressure drop results in ~ 7% additional power consumption.   Refer the table below for impact of Differential Pressure across the separator on performance.  Do you want to know more on the importance of an Air Oil Separator?  Contact the ELGi Air Experts who will guide you further.
