At F. Harley, we specialize in a range of Filtration Solutions designed for Dust Extraction, Flue Gas Filtration and Product Collection applications, to provide ‘Total Filtration Solutions’ to any Dust Filtration problems. With the continuous commitment to the development and introduction of advanced technology products it has resulted in an unmatched product mix and width as follows : 

• a wide range of filter units (reverse pulse jet) covering both stand alone and insertable type to cover multiple point or single point application
• the widest range of filter elements (all manufactured in-house, unlike other manufacturers) covering conventional tubular filter bags, cartridge filters and pad shaped cassette filters, through leveraging it’s background in Industrial / Technical Textiles, with a filter bag division and enjoying technical relationships with world renowned filter fabric manufacturing facilities
• advanced bag cleaning mechanism through incorporation of Nirafon Acoustic Cleaning System (Sonic Horns) which assists in uniformity of cleaning across the bag length, and reduces mechanical stress on the filter media caused by pulsing mechanism.

The entire range of solutions has been a product of assimilated knowledge with the experience gathered in the area of Dust Extraction and Flue Gas Filtration since 1986, through initial technical collaborations with General Resource Corporation, USA (in 1986) and Brind Environmental, UK (in 1995) which has helped create the platform and to put together an unmatched width of customized solutions to deal with the ever challenging areas of dust control and flue gas filtration .

F. Harley & Total Filtration

Experience & Product Range

Filter Media

Behind the company and it’s product range lies a wealth of experience in industrial textile technologies, capable of dealing with the most demanding applications in almost every area of filtration for air pollution control.

One of the most important aspects in air filtration is the correct selection of the filter media considering the process flue gas and dust characteristics, as well as the operating parameters affecting the filter media.

At F. Harley, we work closely with users to analyze their filtration requirements to provide customized ‘SOLUTIONS’ by way of selecting the correct filter media with the appropriate surface finish across both nuisance and product collection applications.

As filter media specialists, we are committed to provide effective and cost efficient solutions and not just in giving you the right size filter bags, but taking you through the entire process of selection suitable for your requirement. We believe a lot needs to be understood by our Customers upon filter fabrics than what is understood at present – we promise to elevate the awareness levels at your end for sure !

Our Product Range – Filter Bags

The Filter Bag range is based primarily on Needlefelt Filter Media for pulse jet bag filter applications. The range comprises Filter Bags made from entire Needlefelt family i.e. Polyester, Polypropylene, Homopolymer Acrylic, Nomex, Ryton / Procon, P84, and PTFE, across a variety of Fabric Constructions and Finishes, with the option of either the conventional Depth or the advanced Surface filtration technique to choose.

Filter Bags – Quality & Manufacturing

Harley has it’s own complete in-house laboratory for testing quality at every point from fabric stage to finished product stage, wherein all the required test’s are conducted

• air permeability
• fabric conductivity
• breaking strength
• fabric weight
• thickness

While manufacturing the filter bags we take into consideration the time / temperature relationship and gas chemistry. Accordingly, the filter bag are manufactured for optimum pinch (bag-to-cage fit) as tendency for excessive flexing and folding, while undersizing hinders cleaning efficiency and hence bag life.

Bag Filter Accessories

With the advantage of manufacturing Bag Filters and having designed and commissioned complete systems, we at F. Harley have an intrinsic sense and understanding of each of the components and their specifications, backed by a strict quality control process to ensure exact replacements or with even improvised specifications.

Our Product Range –Bag Filter Accessories

• Bag Cages
• Sequential Timers
• DP Switches
• Magnehelic Differential Pressure Gauge
• Pulse Valves
• Sonic Horns
• Rotary Airlock

At F. Harley we lay immense stress on this matter as it is very often seen that the subject of Filter Fabrics are not understood even by the very best of engineers in the industry, resulting in the entry of spurious quality of antistatic / conductive filter bags supplied, and accompanied simply by test certificates, without even being aware of the relevant Testing Standards applicable. If you are a user of antistatic / conductive filter bags, our advise would be to contact us and get them tested immediately ! For more information on this ignored subject, click on the attached presentation.

At F. Harley, we would be pleased to elevate your Safety Standards by,

• Ensuring supply of Genuine and Quality Antistatic / Conductive Filter Bags,
• Filter Bag Analysis, and
• Assisting and training your QC Team in the Appreciation and Quality Testing of Antistatic / Conductive Filter Media.

Examples of conductive dusts in different industries:
Power generation: Coal dust
Metalworking: Aluminum dust, magnesium dust, steel dust, zinc dust
Chemical processing: Carbon black, pigment powders, certain polymer dusts.

• Widest Range of Bag Filters suitable for Air Pollution Control and Product Recovery applications.
• In-house manufacturing of Filter Bags and Cartridges
• Availability of both filtration techniques – Depth Filtration and Surface Filtration for appropriate applications.
• Associations with world class filter media companies.
• Unmatched experience and understanding in the subject of Technical Textiles, with the origins of the Company in the above area.
• Complete in – house BIS approved Testing Laboratory for Industrial Textiles
• Activities backed by complete design & engineering, efficient execution personnel and a committed service and commissioning team.
