The vacuum inlet control system, including the inlet valve and other components, together with the permanent magnet frequency conversion control system, precisely regulates the vacuum demand, ensures that the energy consumption of the whole machine is reduced to a minimum, and avoids vacuum overload.

Cooling System

Oversized heat exchanger design, capable of handling an intake gas temperature of up to 46°C and operating in high-temperature, high-humidity environments of up to 46°C.
Variable-speed controlled fans, in conjunction with temperature control valves, ensure that the machine operates within the optimal temperature range.
Stylish machine housing with a rational flow channel design that filters the cooling air, guaranteeing consistent cooling performance over extended periods of use.
Low-speed axial flow fans provide high airflow with low power consumption and minimal noise generation.

Oil Return System

Designed specifically for vacuum systems, it boasts powerful separation capabilities, maximizing the recovery of oil agents.
Incorporates an innovative built-in swirler vane cyclone separation design for more thorough separation.
Features an innovative foldable oil separator core design that maintains the oil content in exhaust gases below 3mg/m³ even under maximum load, minimizing the loss of lubricant.
Offers a selection of lubricants tailored to the specific characteristics of the suction gas, ensuring optimal lubrication, reducing system temperature, and guaranteeing the best separation efficiency of the system.

Intake Pre-treatment System

The intake pre-treatment system is crucial for vacuum systems.
Custom-designed for users' specific processes, the intake pre-treatment system ensures maximum purity of the gas before it enters the vacuum pump, thereby protecting the pump.
The fully stainless steel intake system guarantees durability and applicability in conditions with high moisture or small amounts of corrosive gases, ensuring long-term use without concerns.
The properties and state (temperature, humidity, etc.) of the pre-treated vacuum gas determine the unique requirements for vacuum pump manufacturing. Please communicate thoroughly with Demont or its authorized agents before selecting a model.
