Nederman : High Vacuum

The fume eliminator 840/841 is a small, lightweight, portable extraction unit designed to be carried to the working area. Connected to a welding torch or to an extraction nozzle, the FE 840/841 unit extracts the fume directly at source. FE 840 has a manual start/stop function. FE841 has an automatic start/stop function which starts the unit as soon as the welding begins. It also includes an indicator for filter exchange.

The Nederman L-PAK unit offers highly effective solutions for removing dust and fumes in all types of industries. The compact design makes it easy to place the stationary unit into a restricted work space. Two-stage separation with automatic filter cleaning using atmospheric pressure. Suitable for one to two simultaneous users depending on the application.

E-PAK is intended for extracting welding fumes, grinding dust, swarf, composite material, dust and particles. E-PAK can also be used as a central extraction unit and cleaning system for workstations and machines. Suitable for one to six simultaneous users depending on the application. Contact Nederman for information about our E-PAK that is suitable for explosive dust.

FlexPAK is intended for extracting welding fumes, grinding dust, swarf, composite material, dust and particles. FlexPAK can also be used as a central extraction unit and cleaning system for workstations and machines. Demand-driven vacuum with frequency control makes for energy-efficient operation. F1exPAK can serve two to ten simultaneous users depending on the application.

FlexPAK 800 maintains a higher vacuum and is suited to collecting heavier material such as swarf, stones, gravel and blasting grit where maximum suction is needed.

FlexPAK 1000 maintains a lower vacuum and is suited to extracting welding fumes and grinding dust and for use where a constant airflow is required regardless of the number of users.

Extraction system for fixed installation, with collection bin. Fitted with NVF filter, which is cleaned every time the extractor is switched off. The collected material passes through the cyclone to a container. Powerful ejector intended for collecting heavier material.

Double container system for fixed installation. Fitted with pre-separator for separation of e.g. blasting grit from dust in extracted material. Mounted on silo for storing material. The dust is separated with the NVF filter and collected in the container. The filter is cleaned automatically when the unit is switched off, or this can be done automatically with a timer.

Specifically intended for extracting dust-containing granulates, sand, steel filings, slag and metal recovery. Model supplied with manual discharge valve. The model can be supplied with counterweight or pneumatic valves for auto-matic operations. The automatic NVF filter tolerates very high loadings and is cleaned every time the extractor is switched off.

An extremely powerful vacuum unit for the collection of blasting grit and other granulated material. The combination of high maximum vacuum and powerful airflow enables the transport of material over long distances. Compact design built on a frame, for transport by forklift truck. Fitted with pre-separator. The cleaned material is collected in a silo and can be re-used.

RBU units are used for cleaning, swarf removal, grinding, sanding, welding and in installations where extra extraction power is needed e.g. heavy material or long piping systems. Powerful vacuum units with V-belt driven roots pump. Equipped with accoustic enclosure. As standard supplied with vacuum and discharge silencers, universal valve including vacuum regulator, safety valve and back flush valve. Inlet 0 200 mm. Discharge 0 200 mm.

FlexFilter Dust collector with 2-stage filtration. Central inlet with velocity reducer. Fully automatic filter cleaning. Can easily be equipped with a great variety of filter materials, bins, emptying systems. Standard equipped with circular bags of polypropylene. PTFE or antistatic filters on request.

• Max air flow: 1600 m3/h.
• Max. vacuum: - 50 kPa.
• Separation: - 99.95% (fine dust)
• Inlet/outlet: 0 200 mm.
• Bag type filters designed for dust, welding fume and debris.

Explosive dust A solid piece of any given material is normally safe and non explosive. However, creating a fine dust from the very same material could make it combustible; com-pare a solid piece of wood to wood dust! Furthermore the finer the dust particles are the more "explosive" they become! Many industries handle materials that are or can become explosive! When a combustible material is dispersed as a fine dust and combined with air and an ignition source the potential for a dust explosion increases.

• Synthetic organic dust, such as plastic grinding dust, reinforced plastics and other composite materials, powder paint, cosmetics.
• Metal dusts - Fine dust of aluminium, magnesium, titanium, chromium.
• Organic dust from food industry, such as baking flour, soup powder, spices, sugar.
• Pharmaceutical - Large number of powders used in pharmaceutical industries are explosive.
