Small Diesel Portable Screw Air Compressor Solution

Core Summary

For harsh working conditions such as no electricity in the wild, frequent movement, high dust, and extreme temperatures, we provide an integrated gas supply solution for 5/8 and 6/8 series small portable diesel screw air compressor machines. The entire machine integrates diesel engine power and screw host, with direct drive transmission and intelligent energy consumption control. It is suitable for scenarios such as rock drilling, shotcrete, demolition, and emergency gas supply, and combines portability, reliability, and low maintenance costs to facilitate rapid deployment of overseas projects.

Small Diesel Portable Screw Air Compressor Solution (8).webp

I. Background and Challenges of the 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.

II. Core Products and Parameters

1. 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

III. Standard Configuration and Optional Features

1. Diesel Engine: Changchai / Yuchai / Cummins

2. Screw Host: Self-developed high-precision host (or joint venture brand available as an option)

3. Control System:

(1) Digital display of water temperature, oil pressure, speed, exhaust temperature, and exhaust pressure

(2) Multiple protection and alarm shutdown for the engine and air compressor

(3) Optional GPS/4G remote data interface

4. Protection: Multi-stage filtration + anti-collision shell

5. Mobility: Towing chassis + wear-resistant tires

6. Control: Intelligent monitoring system + automatic protection

7. Structural Design:

2. High-altitude dedicated turbocharged engine (above 3,000 meters)

3. Large-capacity fuel tank (sufficient for 12 hours of continuous operation)

4. Silent type casing (further reducing noise)

5. Multi-outlet valve configuration (simultaneously connecting multiple tools)

IV. List of Compatible Tools (Single Machine Driving Simultaneously)

Model 5/8 (185cfm air compressor) can simultaneously drive:

1 G20 pneumatic chisel + 1 dust blower gun

Or 1 unit of 90-type down-the-hole drill (small hole diameter)

Or 2 pneumatic grinders/tamper machines

The 6/8 model (6 m³/min @ 8 bar) can simultaneously drive:

Two G20 type demolition hammers

Or 1 unit of 115 type down-the-hole drill

Or 1 heavy-duty jackhammer + 1 pneumatic water pump

V. Typical Application 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.

VI. Model Selection Recommendations

- For small-scale rock drilling / demolition (single tool, low flow rate): Choose 5/8, which offers high cost performance and is easy to move.

- For medium-scale rock drilling / shotcrete spraying (multiple tools in parallel, medium flow rate): Choose 6/8, which has stronger power and a wider range of applications.

- For high-altitude / low-temperature environments: Prioritize models with high-altitude compensation and low-temperature heating to ensure stable operation.

- For rental / frequent relocation: Select models with reinforced chassis and intelligent energy consumption control to reduce long-term maintenance and operation costs.

VII. Delivery and After-sales

(I). Delivery Guarantee
