Screw Air Compressor for Mining Application
Product Presentation
Widely used in mines, tunnels, railways, highways, bridge construction, municipal construction, geological exploration, oil drilling and other industries.
Easy-handled humanized operation interface
The operation panel with clarity functions enables the maintenance personnel to operate easily. The unique-designed closed control cabinet possesses a higher insulation grade, which enables the equipment used under field work have a high-qualified dust proof and waterproof character.
Enlarge oil cooler heat radiation area
Oil cooler adopts strip-fin oil cooler made of aluminum alloy, which enlarges the heat transfer area more than 30% and has more residuals, thus makes the compressor work more suitable for the actual conditions of the construction site. Although the design improves the cost of the manufacture, it provides customers a longer period of use, cleaning and maintenance, and the compressors will have a more steady and reliable performance.
Adapt to Special Environment
According to the requirements of outside special working conditions, our products are equipped with constant voltage power protection systems, thus makes the unit operate more steadily. The hull of the unit is designed to separate the side suction and side exhaust systems according to temperature, which guarantees a high working efficiency
