Nederman PAK-M Compact High Vacuum Unit

*Please contact us to discuss your requirements for a bespoke quotation*

The PAK-M is a frequency controlled high vacuum dust collector unit.It is designed for extraction of welding fume (incl. on-torch),grinding-, sanding-, or other non-combustible dust (incl. on-toolextraction) as well as. PAK-M is also suitable for cleaning theworkplace, shop floor or extraction directly from a production line. It is compact enough to fit on a pallet and typical areas of application can be found in welding shops, car body shops, construction industries, industrial laundries etc., generally serving between 1 and 5 simultaneous extraction points.

Typical uses are:

• On tool extraction
• On torch extraction
• Welding robots
• Cleaning applications

PAK-M controls the speed of the motor automatically using a VFD (Variable Frequency Drive) and dP-sensor to maintain a constant vacuum, selected by the user on the control panel - Ideal for on-torch or on-tool extraction but also ensuring minimum power consumption - saving typically 50% energy or more in comparison to units without VFD. The PAK-M can also 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 PAK-M 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. The PAK-M is controlled by the VFD as standard but can be upgraded with a separate PLC for enhanced control- and sensor capabilities. The PAK-M is developed to fit into normally noise sensitive premises thanks to efficient silencers, acoustic enclosure and using the VFD to run at the lowest possible speed needed to maintain the desiredsuction.

To ensure high efficiency filtration and effective filter cleaning, the PAK-M is delivered with a ePTFE filter and with an optional secondary H14 filter. Running the cleaning cycle opens the filter cleaning valve and 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, ensuringminimum total number of cleaning cycles and thereby increasing filter life.

The vacuum and control unit, VAC-M, is also sold separately for combination with another, separate dust separator.

Features

• Low operating costs with energy saving VFD to maintain thedesired vacuum level and 6 000 hours of filter life in most typical applications.
• Low installation costs - unit complete with VFD as starter, control unit and for adjusting the desired vacuum level - no set-up is needed.
• Efficient, dP-controlled or timer-based filter cleaning minimises number of cleaning cycles and gives longer filter life.
• Low noise level with fan mounted in acoustic enclosure.
• ISO 219 04 (W3) compliance, high filter efficiency and possibility to set vacuum level.
