A complete range for extraction and filtration in standard and ATEX applications – replacing E-PAK
The new PAK-M series consisting of PAK-m and PAK-M DX is more energy-efficient while increasing performance in all parameters all thanks to the built-in Variable Frequency Drive (VFD). With several new features and models added, the PAK-M range is more complete than ever.
PAK-M controls the speed of the motor automatically using a VFD and is thereby able to maintain a constant vacuum selected by the user on the control panel. It is ideal for on-torch extraction of welding fume in compliance with ISO 21904 and ensures minimum power consumption. The energy saving is typically 50% or more in comparison to units without a VFD. PAK-M can be set to generate as much vacuum as possible for applications with long piping, material transportation or cleaning. Automatic vacuum valves offer further energy savings by controlling the dust collector with a pilot signal to only provide suction when an operation is ongoing - but can also be used to increase the number of working points if not all are used simultaneously.
PAK-M is intuitively controlled by the panel of VFD as standard but can be upgraded with a separate PLC for enhanced control capabilities. Thanks to the efficient silencers and acoustic enclosure the PAK-M can be fit into normally noise sensitive premises. The VFD runs the PAK-M at the lowest possible speed needed to maintain the desired suction, further reducing the noise level.
To ensure high efficiency filtration and effective filter cleaning, PAK-M is delivered with a ePTFE filter with an optional secondary filter. By rapidly opening a cleaning valve, a powerful blast of reversed airflow is created, efficiently dislodging dust from the filter bags. Filter cleaning is initiated based on how much dust is loaded into the filter (on-demand, dP-controlled) or alternatively, timer based, ensuring minimum total number of cleaning cycles and thereby increased filter life.
Just like the standard version, the PAK-M DX uses a VFD to maintain the vacuum level selected by the user on the control panel – thereby offering substantial energy savings. There are two main versions available; PAK-M DX with a relief panel for release of explosion pressure and flame or PAK-M DX equipped with a flameless venting system that could be used indoors, the latter with variants suited for organic or metallic dust respectively. All versions are offered with two antistatic filter options, both cleanable; a Polyester filter with a Class-M control filter or, a high-efficiency PTFE filter with a H14 control filter, for increased cleaning efficiency and longer filter life in more demanding applications. With safety as main focus, a complete range of sensors alert the user of any malfunction or potentially dangerous situation and minimises impact of a dust explosion.
All in all, the range comprises six DX-variants, all delivered as plug-and-play units, forming a complete EX-range suitable for almost any ATEX application with 1-5 users.
