Small Diesel Portable Screw Air Compressor Solution

 

 

- Challenges: Difficult to lay power lines in the wild, low efficiency and high noise of traditional piston compressors, prone to failure in high-altitude, high-temperature, and high-dust environments, frequent relocation affecting project schedules, and high maintenance costs.

- Goals: No need for power grid, ready to use upon arrival, stable gas supply, full compatibility with various working conditions, low maintenance, and coverage of small and medium flow rate and frequent mobile scenarios.

 

 

- Mining / Quarrying: Rock drilling and blasting assistance, suitable for 5/8 (small mines) and 6/8 (medium-sized mines), stable operation in dusty environments.

- Road / Infrastructure Construction: Concrete demolition, pile foundation drilling, slope protection spraying, quick relocation to adapt to construction nodes.

- Industrial Emergency: Emergency gas supply for factories / construction sites during power outages, ensuring continuous operation of painting, sandblasting, and pneumatic tools.

- Agriculture / Water Conservancy: Farmland irrigation, water conservancy project drilling, mobile and convenient, suitable for remote waters.

- Rental Services: Targeted at engineering rental companies, high cost-effectiveness + low maintenance, improving equipment turnover rate and revenue.

 

 

Core Models Table

Model	Discharge Volume	Working Pressure	Power	Typical Applications
5/8	5 m³/min	8 Bar	36.8 -41kW	Small-scale rock drilling, sandblasting, demolition
6/8	6 m³/min	8 Bar	40-45 kW	Medium-sized rock drilling, shotcrete, emergency gas supply

 

5/8 model

Designed for small-scale construction crews and rental operators, this model emphasizes flexibility, compactness, and low fuel consumption. With a 5 m³/min displacement, it perfectly matches handheld drilling and sandblasting operations. Its power range of 36.8–41 kW offers significant operating cost advantages, making it the ideal entry-level choice for customers requiring frequent relocation and budget-conscious solutions.

6/8 model

Designed for medium-sized mining and tunneling operations, this unit delivers a 6 m³/min airflow capacity, ensuring stable pressure even during simultaneous operation of multiple machines. With a 40–45 kW power reserve, it meets continuous high-load demands. Fast startup and consistent pressure output make it an ideal choice for emergency air supply scenarios, offering reliable performance and superior productivity.

 

 

1.In off-grid operations such as mining, infrastructure construction, and field emergency repairs, the main challenge is the lack of power grid coverage. Traditional piston compressors typically operate at efficiency below 60% and suffer from poor long-term stability. Without a professional solution, worker productivity declines, increasing overall project costs. To address this, we employ a diesel engine directly driving a screw compressor, integrating power generation and air supply into a single unit. The equipment can be equipped with a large-capacity fuel tank, enabling continuous operation for over 12 hours and eliminating the safety risks associated with frequent refueling on site. In terms of installation and maintenance, the unit requires no setup-simply place it on the ground and start using immediately.

 

2.In applications where equipment needs frequent relocation or transfer, the main challenge lies in the time-consuming process of lifting and transporting. On average, each move takes 2 to 4 hours, resulting in significant labor waste, while rough roads easily damage the chassis or piping systems. To address this, our equipment features a three-in-one chassis design that integrates lifting hooks, forklift slots, and tow bars, enabling quick lifting or towing. Additionally, equipped with heavy-duty shock absorption systems and wear-resistant tires, the unit can be deployed immediately upon arrival without requiring any site preparation-simply tow into position and start operating, significantly improving deployment efficiency.

 

3.For applications requiring multiple pneumatic tools-such as jackhammers and down-the-hole drills-to operate simultaneously, insufficient air supply can prevent these tools from functioning properly at the same time or significantly reduce their efficiency, potentially lowering tool performance by 20% to 40% and extending project duration. To address this, we precisely select compressor models based on the total air consumption of all tools used. Specifically, a 5/8 model can power either one G20 jackhammer plus a dust blower, or one 90-type down-the-hole drill; while a 6/8 model (6 cubic meters per minute) can simultaneously drive two G20 jackhammers or one 115-type down-the-hole drill. Additionally, we offer multi-outlet valve kits as an optional accessory, enabling customers to connect multiple tools with independent control, thereby making air distribution more flexible and efficient.

 

Performance Comparison

After implementing this solution, overall fuel consumption in field operations decreased by 20%–30%, with zero installation time ensuring immediate usability. Heavy-duty filtration reduced maintenance costs by 60% and cut environmental downtime by 90%. Relocation efficiency improved, while transport failure rates dropped by 70%. Multi-tool collaborative operation efficiency increased by 30%–50%, and drilling time returned to 12–15 minutes per hole.

 

 

The small diesel air compressor screw type has many features,such us:

Direct connection transmission design: The diesel engine is directly connected to the screw main unit, eliminating the loss caused by belts and gearboxes. The transmission efficiency is higher, preventing belt breakage and gear failures, and reducing the risk of equipment shutdown.

Intelligent protection system: Real-time monitoring of water temperature, oil pressure, and exhaust temperature. In case of exceeding the limit, it will automatically trigger an alarm and stop the machine. It protects the core components and offers optional GPS/4G remote monitoring, thereby reducing the inspection costs for overseas projects.

Extreme environment adaptation: Optional high-altitude-specific turbocharged engine (above 3000 meters). Ensures stable startup and power output in high-altitude and low-temperature environments.

Three-in-One Mobile Chassis: Includes a towing bar, lifting ring, and forklift slot, along with a heavy-duty shock absorber and dust-proof enclosure. It supports three transfer methods: towing, hoisting, and forklifting. It is suitable for various complex road conditions and can withstand high dust and collision environments.

Low operation and maintenance costs: The screw-type main unit has no wear-prone components (no piston rings, valve plates). The annual maintenance cost is significantly lower than that of piston-type machines of the same specification, reducing downtime and increasing investment return.
