PAK-M DX automatically controls motor speed using an integrated Variable Frequency Drive (VFD) and a differential pressure (dP) sensor to maintain a constant vacuum level selected by the user via the control panel.
The system is ideal for direct tool extraction and is specifically designed to minimize energy consumption, typically reducing energy usage by 50% or more compared to units without frequency control. For applications involving long duct runs, material conveying or industrial cleaning, PAK-M DX can also be configured to deliver maximum available vacuum.
Optional automatic vacuum valves provide additional energy savings by ensuring that extraction is supplied only when a process is running. They can also increase the number of connected workstations when not all extraction points are used simultaneously.
The standard PAK-M DX is supplied with an integrated VFD, while a separate PLC can be added to provide advanced control functions and sensor integration.
Designed for noise-sensitive environments, PAK-M DX incorporates efficient silencers, an acoustic enclosure and intelligent VFD control, allowing the unit to operate at the lowest possible speed while maintaining the required vacuum level.
Two filter configurations are available:
- Antistatic polyester filter with Class M control filter
- High-efficiency PTFE filter with H14 control filter, providing improved cleaning performance and extended filter life in demanding applications
The automatic filter cleaning system operates by opening a dedicated cleaning valve, creating a powerful reverse airflow that effectively removes dust from the filter pockets. Cleaning can be activated on demand based on the dust load detected by the differential pressure sensor, or alternatively via a timer. This intelligent approach minimizes the number of cleaning cycles required, helping extend filter life and maintain consistent performance.
The VAC-M extraction and control unit is also available separately for integration with alternative dust separation systems.
Benefits of PAK-M DX
- Low operating costs and reduced energy consumption thanks to the integrated Variable Frequency Drive (VFD), which automatically maintains the required vacuum level. The filtration system also provides up to 6,000 hours of filter life in most typical applications.
- Low installation costs with simple commissioning and no complex setup required to achieve the desired vacuum level.
- Extended filter life thanks to the efficient filter cleaning system, controlled either by differential pressure (dP) or timer, minimizing the number of cleaning cycles while maintaining optimal performance.
- Low noise levels achieved through an acoustically insulated enclosure and optimized fan operation.
- Designed for ATEX applications and equipped with integrated safety features, including:
- Emergency stop function
- Monitored control filter for detection of main filter failure
- Monitored explosion venting system that safely directs explosion pressure to a designated safe area and automatically shuts down the filtration unit
