VALE Bag Filter Timer is a specially developed electronic unit for controlling cleaning cycles of bag filters available in various models to suit different output requirements. The timer energizes a solenoid valve, thus triggering the momentary pulse of high pressure compressed air down into a row of filter bags. This pulse of air will expel the dust from the surface of the filter. The timer closes the valve after a specified time and the filter starts working in the ventilation mode.  Two modes of operation are available namely Continuous cycle and On-demand filter cleaning. In the continuous cycle operation the bags are continuously cleaned. The on-demand operation is based on differential pressure where as the filter bags become dirty, the differential pressure across the surface increases.  If the filters are cleaned based on differential pressure they will be cleaned only when necessary reducing the number of cleaning cycles, thereby extending filter life. Interlocking is provided with the compressed air pressure switch and the timer stops if the compressed air falls below preset level. Both On-line and Off-line types are available. Use of a bag filter timer translates to faster and more effective means of controlling dust at the plant.
We offer Maniks Rotex Asco Astro and Chinese Solenoid Pulse Valve and its spare diaphragm, coils for Reverse Pulse Jet Bag Filters. These pulse Valves are precisely engineered product according to market need. Pilot operated Pulse valve has just one moving part, the Diaphragm. The high speed operation of the Valves besides saving of compressed air, helps to provide shock air wave for dislodging of dust cake from the surface of  Filter Bags. High flow, long life and fast diaphragm action produce reliable & economical operation of the Pulse Valve.
Minimum Efficiency Reporting Value (MERV) is an industry standard that measures the overall effectiveness of air filters. As the MERV rating increases the finer the filtration becomes. With finer filtration, fewer airborne contaminates & dust particles are allowed to pass through the filter. The most common "Airborne Contaminates" that these filters are tested against tend to include pollen, dust mites, mold spores, dust, pet dander, bacteria and tobacco smoke. Below is a table grouping MERV ratings by particle size: 1–4 (> 10.0 μm) Pollen, dust mites, cockroach debris, sanding dust, spray paint dust, textile fibers, carpet fibers Residential window AC units 5–8(10.0–3.0 μm) Mold, spores, dust mite debris, cat and dog dander, hair spray, fabric protector, dusting aids, pudding mix Better residential, general commercial, industrial workspaces 9–12 (3.0–1.0 μm) Legionella, Humidifier dust, Lead dust, Milled flour, Auto emission particulates, Nebulizer droplets Superior residential, better commercial, hospital laboratories 13–16 (1.0–0.3 μm) Bacteria, droplet nuclei (sneeze), cooking oil, most smoke and insecticide dust, most face powder, most paint pigments hospital & general surgery 17–20 (< 0.3 μm) Virus, carbon dust, sea salt, smoke Electronics & pharmaceutical manufacturing cleanroom
Kamakshi Engineering has specialised in FILTER BAG of various types for different types of dust particle. Considering the type of dust, gas, and temperature Filter fabric is selected. We offer FILTER BAGS with Polyester; Polypropylene, Ryton and Nomax fabric. For use in dust collectors we offer FILTER BAGS in following types (1)Conventional BAG FILTER with FILTER CAGE (2)PLEATED FILTER BAG The air velocity should be maintained to allow dust to settle down inside the Dust Collector/ Bag House. Compressed air pulsing through MANIKS / ROTEX /ASCO / ASTRO / equivalent Pulse Valve should be designed for maximum cleaning with low pressure for long life of filters and to save energy.
