Shipyard Touch-Up & Industrial Cleaning
Suitable for deck maintenance, marine coating removal, and localized blasting operations.
HVAC Duct Cleaning & Pneumatic Tool Supply
Provides moderate airflow for air knives, duct cleaning systems, and workshop tool operation.

This low-pressure configuration is optimized for moderate-flow applications and is not intended for high-pressure drilling or multi-nozzle blasting operations. For such requirements, consider 10–13 bar or higher-pressure compressor models.

Peakroc® PRMD-0507 portable Diesel Screw Air Compressor with 5m³/min 7bar(185cfm 102psi). Peakroc® PRMD series have features and advantages as follows:

1. Reliable Power and Strong Structure

This 5 m³/min / 7 bar compressor is equipped with a fuel-efficient heavy-duty diesel engine optimised for moderate output and minimal fuel consumption—perfect for smaller mobile applications like surface treatment or maintenance crews. The compact damped chassis reduces vibration and chassis wear during towing and operation on uneven terrain, ensuring long-term serviceability. The outer shell features 2 mm cold-rolled steel paired with flame-retardant, sound-proof materials—so you get both durability and quieter operation in urban or service-vehicle environments.

2. High-Efficiency Air End and Core Components

At this size, the compressor employs a refined screw air end with SAP rotor profile for high volumetric efficiency. Materials like American specialty steel rotors and Sweden SKF bearings ensure a reliable performance even under frequent start-stop cycles commonly encountered in sandblasting or tool-driven operations. The result: consistent 5 m³/min free air delivery at 7 bar without compromising component lifespan.

3. Clean Air System and Flexible Installation

The two-stage air filtration system removes up to 99.9 % of dust, making this model ideal for abrasive-laden environments such as sandblasting or surface preparation. A high-efficiency oil filter keeps the lubrication system clean and lowers maintenance frequency—important for mobile service units. With its compact size and optional skid-mounted configuration, this unit can be easily towed to job sites, positioned on small platform vehicles, or installed inside service trucks.

Custom Project Case

Project: mobile surface preparation & light-to-medium sandblasting for municipal steel facilities (handrails, brackets, small frames) before repainting. The contractor needed a compact, towable unit with stable 7 bar output, low fuel burn, and reliable daily starts.

Selected: Peakroc® 5 m³/min · 7 bar low pressure Portable Diesel Air Compressor for predictable airflow, easy transport, and continuous duty cycles on outdoor job sites.

Ran single-nozzle blasting with a 4–5 mm nozzle for consistent abrasive flow and
controllable surface profile.
Used a moisture control setup (aftercooler + water separator) to reduce wet abrasive, improve
coating adhesion, and protect tools.
Chose a short hose layout and correct couplers to minimize pressure loss and keep the nozzle
response stable during long runs.
Scheduled simple daily maintenance (filter check + condensate drain) to keep output steady and reduce unexpected
downtime.

Outcome: consistent blast quality, fewer “wet media” interruptions, and stable productivity with a fuel-efficient low-pressure setup—ideal for coating prep and mobile contractors.

Deep borehole drilling / high-pressure applications	High lifting force and stable air at depth	20 bar+

Nozzle Matching (Sandblasting)

Best match (this model): 3–5 mm nozzle for stable abrasive flow
6 mm nozzle: workable only for short bursts, not recommended for continuous duty
Notes: hose length, nozzle wear, abrasive type and humidity can increase air demand

Air Quality Tip (Coating Prep)

For coating prep and cleaner blasting results, add aftercooler + water separator. If you are in humid climates or long hose setups, consider an optional dryer to reduce moisture carryover.

FAQs

1 - Is a 5 m³/min 7 bar diesel compressor suitable for sandblasting work?

Yes. For light to medium sandblasting tasks such as rust removal, surface preparation, paint stripping, or small steel structure treatment, a 5 m³/min 7 bar compressor provides sufficient airflow and stable pressure. For large industrial sandblasting rooms or continuous heavy operations, 10 bar or higher flow models are recommended.

2 - What kind of sandblasting nozzle size is suitable for this compressor?

This compressor can support 3–5 mm nozzles comfortably. If using a 6–8 mm nozzle, the air volume might not be sufficient for continuous blasting. Smaller nozzle sizes ensure steady abrasive flow and reduce fuel consumption.

3 - Can it run continuously for long hours during surface treatment?

Yes, as long as proper ventilation and engine oil levels are maintained. The diesel engine and screw air end are designed for continuous duty. However, during dusty sandblasting work, regular cleaning or replacement of the air filter is necessary to prevent clogging.

4 - What fuel consumption should I expect during sandblasting operations?

Under 70–80% working load, fuel consumption is approximately 5–6 liters per hour. Actual usage depends on ambient temperature, blasting intensity, and nozzle size.

5 - Can this compressor power other tools besides sandblasting equipment?

Yes. It can be used with pneumatic grinders, impact wrenches, small jackhammers, rock drills, and air blow guns. The 5 m³/min flow rate is commonly used by maintenance teams, painters, small fabrication workshops, and mobile repair vehicles.

6 - Is it easy to transport to job sites? Does it require registration for road towing?

The unit is designed with a towable trailer chassis, lifting ring, and parking brake, making it suitable for on-site transport. For towing on public roads, local regulations apply—some countries require lighting, license plate bracket, and registration. For internal factory or construction site use, no registration is necessary.
