Overview
Product Overview
The Two Stage Air Compressor range uses reciprocating compression in two successive stages to support higher-pressure compressed-air duties. The belt-driven receiver-mounted arrangement combines the compressor pump, motor, controls and storage tank in an integrated industrial package.
The supplied range covers motor ratings from 3 to 25 HP, two- and three-piston configurations, listed piston displacement from 9.75 to 81.95 CFM and receiver capacities from 175 to 500 litres. All listed variants show a source-stated working pressure of 12.30 Kg.
Two-stage compression makes these machines suitable for applications requiring greater pressure or more demanding service than a typical single-stage unit. Potential duties include industrial pneumatic tools, service facilities, fabrication shops, production machinery and other uses within the selected compressor's delivered-air capacity and duty-cycle limits.
Model selection should be based on confirmed free air delivery at the required pressure, simultaneous air demand, operating hours, duty cycle, receiver volume, electrical supply and ambient conditions. Suitable drainage, filtration, drying and air treatment should be provided for the application.

Source note: Working pressure is reproduced as "12.30 Kg" exactly as shown in the supplied sheet, which does not state an area denominator. The source also lists two RMT-6900 configurations. Confirm the rated pressure in a standard pressure unit, exact model configuration, free air delivery, duty cycle, electrical supply and receiver certification in the final technical quotation.

FAQs
Frequently Asked Questions
What is a two-stage air compressor?
It compresses air in two successive stages, typically with intermediate cooling, to achieve higher pressure more efficiently than a comparable single-stage arrangement.
What motor sizes are available?
The supplied range includes motor ratings from 3 to 25 HP, depending on model and configuration.
What piston-displacement range is listed?
The model table lists piston displacement from 9.75 to 81.95 CFM. Confirm actual free air delivery at the required pressure for correct selection.
Which receiver capacities are available?
The supplied configurations cover receiver capacities from 175 to 500 litres.
Why are two RMT-6900 variants shown?
The supplied sheet lists one RMT-6900 with a 15 HP motor and 62.20 CFM displacement, and another with a 20 HP motor and 81 CFM displacement. Confirm the exact offered configuration when ordering.
When should a two-stage compressor be selected?
It is generally selected when the application requires higher working pressure or demanding industrial service. Final selection must use confirmed air delivery, pressure and duty-cycle data.
What routine maintenance is required?
Typical work includes checking oil, draining condensate, servicing intake filters, inspecting belts and guards, cleaning cooling surfaces, checking interstage components and leaks, and testing safety devices according to the manual.
What details should be provided with an enquiry?
Provide required pressure, air consumption, simultaneous tool use, daily operating hours, preferred receiver size, required air quality and available voltage, phase and frequency.
