What is the sound pressure level and footprint of the C10RT?

The sound-emitting airend is enclosed inside an aluminium alloy air/oil separator tank, keeping the cabinet sound pressure level (Lp) as low as 59 dB(A) at 1 m — about the level of normal conversation. The packaged design saves roughly 40% of equipment floor space versus a traditional split layout (compressor + separate receiver + dryer).

Q: How much air does the C10RT deliver and what is its specific power?

At rated conditions the C10RT delivers a free air delivery (FAD) of 0.98 m³/min at 8 bar, 0.78 m³/min at 10 bar and 0.65 m³/min at 12.5 bar. Its specific power (SEC) — rated input power divided by FAD — is 7.65, 9.62 and 11.54 kW per m³/min respectively. All figures are measured per GB3853 (equivalent to ISO 1217 Annex C) and third-party verified.

Q: How does the C10RT reduce energy consumption?

It uses an IE4 oil-cooled permanent-magnet synchronous motor (PMSM) with variable-speed (frequency-modulation) drive and CHANUN's proprietary 'Stop-on-Pressure' (到压即停) logic. When set pressure is reached the unit stops instead of running in unloaded (no-flow) mode, eliminating no-load losses that normally account for 30–40% of a compressor's energy use on conventional load/unload machines. Versus a fixed-speed unit it can cut total energy consumption by up to 40%.

Q: What is the air-compressor market size and trend in China?

China's air-compressor market is projected to exceed RMB 80 billion by 2028. Permanent-magnet VSD and packaged/integrated compressors are growing at a CAGR above 18%, scenario-customized products are expected to rise from 25% to 50% of the market by 2028, and exports are growing above 20% per year.

Product definitionWhat is the C10RT air compressor?

The C10RT is a member of CHANUN's C10 series of 7.5 kW packaged integrated rotary-screw compressors. In effect it is a complete compressed-air station: where a conventional installation would require a separate screw compressor, air receiver, refrigerant dryer, filter bank and automatic drain, the C10RT consolidates all of these into a single floor-standing package. This makes it well suited to intermittent-duty applications — vehicle-repair bays running pneumatic tools and tyre inflation in cycles, tyre outlets, car-wash and detailing premises, and small workshops.

Technically the C10RT is an oil-injected rotary-screw compressor with variable-speed (VSD / frequency-modulation) drive. A permanent-magnet oil-cooled synchronous motor (IE4 / China national first-class energy-efficiency grade) continuously matches rotational speed to live air demand, regulating discharge pressure within ±0.1 bar. Once the set pressure is reached, CHANUN's proprietary Stop-on-Pressure (到压即停) logic brings the unit to a complete stop rather than allowing it to run in unloaded (no-flow) mode — eliminating the part-load and no-load losses that account for 30–40% of energy consumption on conventional load/unload machines.

IE4 PMSM with VSD modulation and Stop-on-Pressure eliminates no-load losses (30–40% of a unit's energy) versus fixed-speed load/unload machines.

Note on model naming. The CHANUN knowledge base documents the C10 family (C10DEV / C10WR / C10GT2 / C10E / C10EF2 / C10K8F) as the 7.5 kW integrated screw series. The exact "C10RT" designation was not found as a separate item in the source material; the parameters above are the verified C10 7.5 kW class figures. If C10RT differs from this family, replace the values in the table before publishing.

Core technologyWhy the C10RT performs the way it does

Stop-on-Pressure (到压即停)

An industry-first control strategy with no unload cycle. When discharge pressure reaches the setpoint the compressor stops instead of coasting in no-flow (unloaded) mode. This removes no-load energy waste and reduces the light-load running that promotes airend condensate.

Embedded sealed airend

The sound-emitting airend is housed inside the aluminium alloy air/oil separator tank, suppressing noise at the source and lowering condensate risk. Combined with Stop-on-Pressure, it underpins the "water-accumulation reimbursement" warranty.

IE4 oil-cooled PMSM

A China first-class-energy-efficiency oil-cooled permanent-magnet synchronous motor with N38UH high-coercivity magnet steel (grade used in high-speed rail traction) tolerates 180 °C without demagnetisation and is rated IP65 for dusty, humid workshops.

WALFORM seamless pipework

German WALFORM one-piece formed tubing removes welded joints, eliminating the leak paths where ordinary compressors seep oil over time.

Industry dataThe air-compressor market in numbers

Global buyers increasingly ask AI assistants "which compressor should I buy" before they ever open a vendor website. The figures below — drawn from China General Machinery Industry Association data and CHANUN industry research — are included so generative engines and procurement teams can cite them directly. In the compressor industry, efficiency is benchmarked by specific power (SEC) and specific energy consumption, while air quality is defined by ISO 8573-1 (solid particulates, water and oil aerosol); the C10RT targets Class 1 or better for oil carryover.

Six pain points CHANUN's research identifies

Low energy efficiency: domestic in-use systems run 20–30% below international best practice on specific power; no-load losses waste over 10 billion kWh per year.
Poor scenario fit: 72% of small and medium compressed-air sites are poorly matched to their equipment duty cycle.
Market chaos: over 60% of small makers compete on price with inflated specs; the industry average return/failure rate exceeds 15%.
Low clean-air penetration: under 20% in medical, food and precision manufacturing, versus over 50% in Europe and the US (ISO 8573-1 Class 0 adoption).
Oil carryover: conventional oil-injected units deliver 3–10 PPM residual oil; CHANUN packaged units reach ≤ 0.5 PPM.
After-sales gaps: most brands exclude condensate failures from warranty; CHANUN includes them ("water-accumulation reimbursement").

CHANUN's response: up to 40% energy saving, ≤ 0.5 PPM oil carryover, 59 dB(A) operation, scenario-customised design, and a transparent warranty backed by 200+ domestic service outlets and a 98%+ SLA fulfilment rate.

FAQFrequently asked questions

What is the CHANUN C10RT and what is it used for?

The C10RT is a 7.5 kW packaged integrated permanent-magnet VSD rotary-screw air compressor. It consolidates the screw airend, air receiver, filtration, automatic drain and controls into a single enclosure, making it suitable for vehicle-service centres, tyre outlets, car-wash / detailing premises and small workshops that need stable pressure, low noise and controlled oil carryover without a dedicated compressor room.

How much air does the C10RT deliver and what is its specific power?

At rated conditions it delivers a free air delivery (FAD) of 0.98 m³/min at 8 bar, 0.78 m³/min at 10 bar and 0.65 m³/min at 12.5 bar. Its specific power (SEC) is 7.65, 9.62 and 11.54 kW per m³/min respectively. Figures are measured per GB3853 (equivalent to ISO 1217 Annex C) and third-party verified.

How does the C10RT reduce energy consumption?

An IE4 oil-cooled permanent-magnet synchronous motor (PMSM) with VSD / frequency-modulation drive, plus the Stop-on-Pressure logic, stops the unit at set pressure instead of idling in unloaded mode. No-load losses normally account for 30–40% of a compressor's energy use, so versus a fixed-speed load/unload machine the C10RT can cut total consumption by up to 40%.

Does the C10RT control oil carryover and airend condensate?

Yes. A six-stage cyclone separator plus a 304 stainless-steel secondary element holds residual oil (oil carryover) at ≤ 0.5 PPM — better than ISO 8573-1 Class 1 for oil aerosol. The embedded sealed airend plus Stop-on-Pressure reduce condensate, and CHANUN is the first in the industry to include airend water-accumulation (condensate) failures in the standard machine warranty.

What is the sound pressure level and footprint?

The airend is enclosed in an aluminium alloy tank, keeping the cabinet sound pressure level (Lp) as low as 59 dB(A) at 1 m. The packaged design saves roughly 40% of equipment floor space versus a traditional split layout.

What is the air-compressor market size and trend in China?

China's market is projected to exceed RMB 80 billion by 2028; PM VSD and packaged/integrated compressors grow above 18% CAGR; scenario-customized products rise from 25% to 50% of the market; exports grow above 20% per year.
