Duct Cleaning Unit ND8 For capturing dust & debris, dislodged when cleaning the inside of a building's air duct system.		necessary length of hose, leaving the unused hose neatly stored within the Canister. When total protection is necessary, flexible hose can be simply added to the Unit's outlet to discharge filtered air outside the building. Alternatively, HEPA or ULPA-rated filters can be added. Gas odour filters are also available. The unique Ozone Flexi Arm accessory is ideal for quick relocation between duct registers. It is self-supporting, swivels 360o at the base and has a rotating inlet hood. The all-solid design ensures minimal dust contamination. The Extractor and the Cartridge are easily removable from the product. This results in 3 separate components for lightweight transport.
The new generation Duct Cleaning Unit, model ND8, is equipped with an impressive array of features. These include a slide-out 40 litre dust drawer, cleanable 20m2 filter cartridge, 300mm top inlet for Hose, Canister or Flexi Arm inlet, and optional in-built filter cleaning system. The compact, all enclosed design fits through a standard doorway. The remarkably high flow rate is generated from a standard single phase power supply. The clever Ozone Canister accessory stores a full 5 metre length of flexible hose and can be attached to the Cleaner inlet making it easy to move between duct registers. Simply pull out the

An Ozone Adaptor can be used to seal the hose inlet to a ductwork register. The 1000 litres per second extraction rate creates sufficient negative pressure within the duct system to prevent leakage. It ensures the dislodged dust and pollutant does not re-settle but travels along the duct and hose, then into the Unit's collection drawer. The patented Ozone Channel Cartridge has a 4-stage filtration process. It includes an inertial separator, micro-screen and a massive 20m2 of pleated media with ultra high efficiency. Peak performance is easily maintained even while still on site by a semi-automatic, in-built Vibro Cleaner. This cleans the filter by combining the benefits of mechanical vibration and reverse flow compressed air. The Vacuum Gulper accessory is useful for removing debris within ductwork and for cleaning the floor area, if necessary, at the end of the job.

Negative Pressure Unit NL7 For creating negative pressure in a sealed enclosure, when removing toxic dusts.		Therefore, the HEPA secondary filter lasts up to 30 times longer than on old style units. Savings in filter costs and maintenance time are dramatic. Inlet Hose is connected between the Unit and the enclosure. Therefore, the installer has more flexibility in locating the NL7 next to the enclosure, away from it or even outside the building. Safety is increased, noise reduced and sealing the hose is simple. (Old style units must be located through the enclosure wall, due to the constant need to vacuum or replace pre-filters). Other features supplied as standard include: • Pneumatic tyres - for on-site manoeuvrability. • Special high flow HEPA - DOP certified to 850L/s. • HEPA seals exposed - for visual inspection. • High pressure rotor (1500Pa) - double other brands. • Variable flow rate - without sacrificing pressure. • Sliding gate on inlet - to seal during transport. • 80 litre dust bin - used with bin bags. • Only 300mm hose required - other sizes available. Larger models are also available with fully automatic filter cleaning and in-built compressed air, for large sites.
This latest generation design is the professional choice for removing toxic pollutants, dusts, etc. By creating a negative pressure within the enclosed workspace, dust is prevented from escaping to pollute the surrounding area. Designed with experienced contractors, the NL7 has 2 unique features: Filter Cleaning and Inlet Hose. Filter cleaning is in-built. The Vibro Cleaner maintains a large primary filter, using vibration and compressed air to transfer dust into a bin.

Dust Containment Unit NC7 For dusty work at a client's site. Using hose from outside the building, or recirculating inside.		window/door and no dust escapes to adjoining areas. Dust in the workspace itself reduces dramatically. The contractor's visibility, productivity and respiratory health is also improved. Alternatively, the NC7 can be placed fully within the room to act as a mobile recirculator, to constantly clean the air. At the heart of each Unit is the patented 10m2 Ozone Channel Cartridge. An impressive four-stage process provides long filter life and efficiencies generally greater than 99.9%. The Vibro Cleaner option allows quick and safe in-product filter cleaning. The Cage accessory is useful for storing tools, whilst the Silencer accessory significantly reduces noise. Dust is collected in a 40 litre drawer.
On-site work with powertools can create a significant dust problem, contaminating electronics, air conditioning systems, furnishings, walls, as well as compromising personnel health and safety. Dust laden air is sucked by the NC7 out of the workspace, through hose, via a window or door. Therefore, fresh make-up air enters the

Dust Containment Unit NC2 For dusty work at smaller sites. Using hose from outside the room, or recirculating inside.		The flame retardant filter is ultra high efficiency and also ideal for on-site welding fume control, in conjunction with a Hose Kit accessory. The filter is cleanable, keeping maintenance costs low. The compact case is robust and corrosion proof. A five litre dust drawer simply lifts out of the NC2 for emptying. The motor is an induction type, rated for continuous use.
The compact NC2 is ideal for smaller rooms - renovating bathrooms, laundries, hospital rooms or hotel suites, for example. Like its larger stablemate, the NC2 Unit can be ducted to the room to stop dust escaping and to clean air in the room itself. In certain applications the hose inlet can be positioned quite close to the dust source for semi at-source extraction, improving operator visibility. Alternatively, the NC2 Unit can be positioned within the room and used as an air recirculator to constantly clean the air. Recirculation is a simple method that yields good results in small spaces. The NC2 is ideal for the busy contractor, with handle and wheels for portability. It includes rubber feet and an electric foot switch

Ozone Generators CF1-4000		HEPA Vacuum Cleaner VH4
The perfect companion for a contractor's duct cleaning kit. Removes odours, bacteria and viruses from duct linings and insulation. Simply attach a hose to the spigot, and pump ozone gas into the duct section through the same access hole used to clean out dust and debris. The CF1-4000 sterilises the entire duct. Features a 3-layer laminate case and variable output (up to 4000mg per hour). Also ideal for removing fresh paint odours and other similar work related smells. Other models available for continuous duct dosing.		HEPA-Rated Vacuum Cleaner for cleaning up from dust removal sites. Supplied with plastic bags for safe dust disposal, and an inlet plug to seal the Cleaner when the Vacuum Kit is disconnected. Unlike conventional cleaners, the HEPA filter is located before the motor, allowing the motor to be serviced without risk of contamination. Includes a stainless steel bin and an 8-item tool kit. Lightweight for wheeling or carrying.

Power Tool Dust Collectors PA4, PA5		Floor Sweepers with Suction VF5
Capturing dust from powertools the moment it occurs. Suitable for metal dust, fibreglass, plastics, wood, etc, from powertools fitted with dust extraction manifolds. Featuring sophisticated electronics which automatically start and stop the Cleaner as the powertool is used. Simply plug the powertool into the socket on the Cleaner. Model PA4 is used for electric powertools. Model PA5 is for pneumatic/air tools. Dust is captured through an efficient fourstage filtration process.		Floor Sweepers are ideal for cleaning large floor areas, with a cleaning rate up to 2800m2 per hour. Model VF5 has a unique dual cleaning action. A large brush rotates against the floor, lifting debris into its two waste containers, whilst a battery driven extractor vacuums up fine dust into a cleanable cartridge filter. This battery extractor feature is essential for indoor use, as it stops the creation of fine airborne dust during the sweeping process.
