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.

FAQs
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.
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.
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.
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.
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.
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.
