Frequently Asked Questions
The KEP series requires access to an industrial power supply (380V/415V/460V). If your site lacks electricity, we recommend our KDS Series (Diesel Portable). However, if a generator is available on-site, using the KEP series is more fuel-efficient and environmentally friendly than using a diesel-driven compressor directly.
Maintenance is significantly lower. Without an internal combustion engine, you avoid frequent oil and filter changes for the engine. You only need to maintain the screw air end and the electric motor, which reduces overall maintenance costs by over 50% and minimizes downtime.
Yes. Our units feature high-protection motors (IP54/IP55) and reinforced dust-proof electrical cabinets. The heavy-duty intake filtration system is specifically designed to prevent dust and moisture from damaging the internal components in extreme conditions.
Absolutely. KOTECH provides customized motor configurations. We can supply units compatible with 220V, 380V, 415V, 440V, or 460V at either 50Hz or 60Hz to meet the specific electrical standards of your region.
Yes. The KEP series is built on a heavy-duty trailer chassis with a high-strength suspension system and a reinforced tow bar. Whether it’s high-speed towing or moving across uneven mining surfaces, the structural integrity of the piping and components remains protected.
Selection is primarily based on your required Air Delivery (cfm/m³/min) and Working Pressure (bar/psi). For instance, shotcreting usually requires 10-13 bar, while pneumatic drilling might need higher pressure. Our engineers are available to provide a free technical consultation to match the perfect model to your tools.
