ELGi PG Series electric portable screw compressors deliver quiet, emission-free, and energy-efficient solutions for construction, mining, and industrial applications.

ELGi’s PG Series Electric Portable Screw Compressors are engineered to deliver high performance while setting a new benchmark in eco-friendly, portable compressed air solutions. Compressed air solutions are important for construction, mining, and oil and gas industries. Designed for industries where clean energy, reduced emissions, and operational efficiency are top priorities, these compressors combine advanced technology with a compact footprint.

In sectors such as construction, mining, and oil and gas, compressed air is a critical utility. Drilling presents both technical and commercial challenges, demanding solutions that deliver speed, reliability, and efficiency. ELGi’s PG Series addresses these needs across a wide range of applications, including DTH drilling, oil and gas exploration, tunnelling, pigging, sandblasting, quarrying, piling, laying of fibre cables, and road and bridge construction.

The PG Series Electric Portable Screw Compressor (126-550 CFM, 102-232 psi(g)) is best suited for environmentally conscious customers. The air compressors are ideal for work environments where electricity is readily available in work environments that require quiet and emission-free conditions. The compressor has an electric system powered by a three-phase TEFC squirrel cage motor with ‘F’ class insulation.

Key Benefits

• Energy Efficiency: The η-V rotor profiles are designed to maximise energy efficiency, hence minimising energy expenses.
• Durability and Protection against Corrosion: The compressor canopy is made of powder-coated industrial-grade steel, and the cool-box design allows cool air to enter the rear of the compressor (in closed-door operations) and wash over internal components to keep the internal temperature low and extend component life.
• Manoeuvrable in Small Spaces: The PG series is compact and manoeuvrable in small spaces, making it capable of short radius turns in narrow spaces.
• Increased Operational Life: It is ideal for dusty environments, as the two-stage filtration system keeps dust out of the compressor and engine.

These compressors are best-suited for standard pressure applications, including powering breakers and tools in marble, granite, and blue metal quarries, and more specialised applications such as sandblasting, pigging, drilling, and optical fibre blowing, as they are engineered for high uptime and easy manoeuvrability. The user-friendly controls and robust design ensure both operator comfort and lasting performance.
