The Econojet Reverse Pulse on-line cleaning extractor is designed to provide maximum performance where high volumes and loading demands need to be met with an extracted air volume ranging of up to 12,000 m3 /hr (dependent on installation) and the flexibility of rotary valve discharge  to  a more accessible waste collection point .

 The extractor is also fitted with an explosion relief panel manufactured to the standard EN1497:2006 and fitted with rupture indicators on each panel in order that, in the event of a rupture , a signal is is relayed to the control panel to initiate shutdown of the fan set fitted to the filter unit

 The Heaton Green Econojet can accept a wide range of filters in a wide range of filter fabric materials - offering a filter to suit all types of applications from heavy aggressive dusts to light smoke and fumes.

 The unit houses 36 filter bags @ 1500 mm in length

 Where you have a range of machines with high dust volumes, a wide variety of pressure and flow requirements and you require constant 'on-line' filter cleaning the Econojet is the answer. It's also ideal when a high-volume continuous extraction process is required from a full production line.

 Econojet technology provides a consistent high level of dust extraction to ensure effective removal of waste material generated by the likes of foundry, high speed, food, woodworking, CNC machinery or similar 'high pressure required' applications.

 The advanced reverse pulse technology shrinks the size of the dust extractor while still providing all of the benefits of online cleaning and performance. This allows a much smaller machine footprint and reductions in operating costs.

 Periodically a bank of filters is cleaned in a sequential pattern by a high speed ( 1/10th second) pulse of compressed air. The effectiveness of this pulse is a design advantage and combined with the carefully calculated filter spacings and scientifically designed flow of air over the filters means superior performance and results.

 The Econojet high pressure, high efficiency 7.5 kW / 10 Hp fan, provides excellent waste material removal at the same time, reducing the levels of work place dust, and improving tooling and machine life.

 The body is designed and built from 3mm steel with rolled reinforcements and clad in powder coated steel panels to enable the units to be installed either inside the factory or outside where it’s fully sealed design makes it weather proof.

The reverse pulse design protects against any abrasive dust damage to the extraction fan, with its negative pressure extraction chamber whereby air is ‘drawn through the pre-separation chamber, then into the filter chamber rather than the other way round where it is often blown in under pressure, so no dusts actually will ever come into contact with the fans impeller.

 The Heaton Green Econojet is fitted with flat pad filter bags which have an advantage over cartridge type filtration as they can handle a higher dust loads per cubic meter of extracted air, and can handle  course or fibrous materials.
