Introduction:-
The beginning of the dust collector has allowed corporations to effectively capture mobile 
particulate from Associate in nursing air stream. This has become more important for several 
reasons. First, containing particulate toxic or not is critical to produce a healthy and clean work 
atmosphere. Second, increasing native and world awareness of pollution, containment and also 
the method dirt in industrial applications has stressed the importance of dirt collectors. Finally, 
increasing laws have pressured corporations to properly style, install, operate and maintain 
dust collection instrumentation.
Maniks is the dust collector parts manufacturer of Pulse Diaphragm Valve and Pilot Operated 
Valve for reverse pulse jet bag filters, and offers precisely designed product that customers 
need. These dirt Collector Valves has only one moving half known as as Spare diaphragm. The 
dust collector parts manufacturer called Maniks Pulse Diaphragm Valve has exclusive 
springless construction. Because of such style it provides quick gap and shutting which 
enhance the lifetime of the valve. Due to high speed operation it not solely saves the 
compressed gas however additionally helps to produce shock air wave for removal of dust 
from filter baggage. Long life, High flow, and quick diaphragm opening and closing activity 
result into reliable and economical operation of Pulse Diaphragm Valve.
To ensure a dust collector is functioning properly, you need to perform periodic inspections, as 
well as repair and replace damaged or malfunctioning equipment. A routine examination and 
maintenance program can boost your equipment’s performance and life. To maintain the health 
and effectiveness of your dust collector, follow our useful list of procedures.

1. Make an Inspection/Maintenance Program 
A typical program consists of a schedule for periodic 
inspections that area unit performed on a daily, weekly, 
monthly, semi-annual and annual basis. 
Failing to sporadically examine the dust collector will 
hurt its performance. Subsequently, the dust collector 
may not meet EPA outlet emissions standards.
2. Don’t Overload Suggested Pressure Drop 
Typically referred to as differential pressure, it’s the quantity of static resistance 
across filters once operative a positive- or negative-pressure dust collector. 
Pressure drop, typically determine in inches of water column (in w.c.), is a good 
indicator of the amount of dust that has collected on the filter media and, if 
continually monitored, the condition of the filters.
New filters have rock bottom pressure drop as a result of the inherent 
permeableness of the media. As the baggage develops a dust cake, some 
particulate embeds itself into the filter media, increasing pressure drop 
accordingly. The filtering of the airstream through this accumulated dust cake 
provides high-efficiency assortment of fine particulate. In fact, the best potency a 
dust collector offers is simply before the improvement is initiated. However, high 
differential pressures will cause filter media bleed-through or bright. Therefore, 
don't to exceed the manufacturer’s suggested operative pressure drop.

3. Checking Dust Collector Valve Operation
Dust Collector valves are functioned by integral solenoid pilot operator. 
The Trapped air above pulse valve diaphragm is immediately used up 
causing fast opening of pulse diaphragm valve, When the valve is 
energized. Air comes out through bleed hole of main pulse valve to 
balance the pulse diaphragm valve pressure and immediately closes the 
valve, when the pilot valve is de-energized.
The possessing duty time cycle for ac voltage is 20% and for DC voltage 
is 10 %. This indicates energized time is maximum 1/5th of de-energized 
time for AC and 1/10th for DC voltage.
Dust Collector Pulse diaphragm Valve can be mounted in any position 
for smooth operation. However smart engineering follow is to remain off 
from scale and targeted water getting into valve body for hassle free 
performance, business commonplace finish connections of BSP area unit 
provided.

 4. Ensure Cleanup System Functions Properly
Equipment use a range of cleaning systems to dislodge 
accumulated dust cake from the filter media. Systems include 
reverse air, shaker or pulse clean. Regardless of the design of 
improvement, it's imperative that this system operate properly in 
the slightest degree times. Without a good improvement system, 
dust can still build upon the luggage. The result are Associate in 
Nursing inflated pressure drop and reduced
volume of ventilation air at the pick-up points. Further, airstream 
velocities within the ductwork can decrease and cause dropout of 
dust within the ducts. This may choke the complete system and 
render it ineffective.
5. Anticipate Visible Emissions
This includes any particulate that may be seen discharging from the 
exhaust stack. These emissions indicate a breach during a seal or a broken 
(torn) filter. In either case, you must find and correct the leak instantly. 
Not only will the emission cause a health concern and damage the 
property outside the plant, but it may also bring about monetary fines 
imposed by local, state and federal environmental agencies. Additionally, 
fans located downstream of the collector can be damaged from abrasion 
or become imbalanced if you don’t correct this condition quickly.
Continually monitor exhaust from the dust collector. Along with visual 
inspections, consider incorporating a broken bag detector into the clean 
air ductwork. If a bag begins to fail, or there’s a leak in the bag seal, 
you’ll detect the particles that bypass the media. Typically, these 
detectors use turboelectric technology. These devices will be wired to 
Associate in Nursing alarm horn, siren or PLC.
 6. Choose The Suitable Exhaust Fan
Dust collection systems need an fan to accelerate 
ventilation air from the purpose of pick-up, through the 
ductwork and dust collector filter media and out the 
exhaust stack. 
Fans are selected to accommodate volume (SCFM) and 
pressure drop throughout the system. Calculate the 
pressure call in evaluating the static resistance of the dirt 
collector, ductwork and pick-up points/hoods.
