Reciprocating Compressor
The Reciprocating Compressor (Product Code: SLE/EFM/07) is a trolley-mounted test module containing a small compressor, an air receiver and instrumentation, used to show students how a piston compressor turns shaft power into compressed air. A valve and orifice on the receiver outlet let the class set delivery pressure and measure the mass flow of air leaving the system. The module is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as lab equipment for technical institutes, engineering colleges and industrial training centres.
Specifications
| Parameter | Detail |
|---|---|
| Module contents | Small reciprocating compressor, air receiver and instrumentation |
| Mounting | Robust, mobile trolley |
| Air path | Air enters the compressor and is delivered under pressure to the receiver |
| Pressure control | Valve releasing receiver pressure to atmosphere through an orifice; the valve sets receiver pressure and hence flow rate |
| Flow measurement | Orifice for accurate measurement of outlet air mass flow rate |
| Speed | Fully variable up to the maximum allowable for the compressor |
| Power measurement | Speed, torque and power absorbed measured by the separate Universal Dynamometer |
Typical Use
Reciprocating compressors supply the air behind air tools, paint spray equipment, pneumatic actuators and control systems, so this module links directly to what students meet in workshops and plants. In a typical test the compressor runs at a chosen speed while the outlet valve is closed in steps; at each receiver pressure the class records mass flow from the orifice and the power absorbed from the dynamometer. The resulting curves show how the flow the compressor can deliver falls as delivered pressure rises, and let students calculate volumetric efficiency and the power needed per unit of air.
Repeating the series at different speeds shows the effect of running a compressor faster or slower, a practical point for anyone who will later size or operate a plant compressor. As engineering educational equipment for Indian diploma and degree programmes, the trolley mounting lets one module move between rooms. Release receiver pressure fully after each session, keep the orifice clean, and keep hands clear of moving parts while the machine runs.
Manufacturer
This compressor module is produced by Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer whose apparatus is sold under the ScienceLab name. The company serves teaching laboratories across engineering and the sciences; visit our company profile to learn more.

Frequently Asked Questions
What is included in the Reciprocating Compressor module?
A small compressor, an air receiver and instrumentation, all mounted on a robust mobile trolley.
Is the Universal Dynamometer part of the module?
No. It is a separate unit that measures speed, torque and the power absorbed by the compressor.
How is air flow measured?
Air leaves the receiver through a valve and an orifice; the orifice allows accurate measurement of the outlet air mass flow rate.
How do students change the operating point?
The valve sets the receiver pressure, and hence the flow rate, while compressor speed is fully variable up to its maximum allowable value.
What are the maximum pressure and receiver volume?
These ratings are not published on this page. Please ask our team for the figures before planning experiments.
What warranty applies?
Warranty terms are confirmed on each quotation.
Can you deliver outside India?
Yes. We supply institutions in India and international markets.
