Custom-built baghouses...we built them for other manufacturers for years.
Now we build them for you.


Why not choose a baghouse that meets the exact requirements of your plant at a reasonable price? You can't buy a better combination: baghouse, custom ductwork, knockout box, engineering, and service. Stansteel is chosen where codes are most rigidly enforced and where maximum daily production is a basic financial necessity. We've built, rebuilt, and updated hundreds of baghouses, so we know what works best. We build to your exact requirement.
   
Stansteel® Pulsemaster Baghouses - Custom Features:

The Stansteel Baghouse has been recognized for many years as a leader in the field from both a rugged construction standpoint, extremely low maintenance and equipped to handle the rigors and varying conditions of all types of hotmix asphalt plants.

Many hotmix producers do not realize the absolute critical nature of the baghouse from the standpoint of delivering the needed air and oxygen and removing products of combustion from the process.

As Stansteel engineers and application specialists evaluate the correct baghouse/air system/combustion system for a process, there are a number of factors that are considered in the evaluation. All of the critical operating conditions such as elevation, moisture content, amount of dust and fines and other special handling considerations. We look for special fugitive venting and exhausting items such as steam explosion vents from adding RAP to certain areas or even a special handling of additional fillers such as lime or the metering of dust back in the process.

The induced draft fan that is supplied with the baghouse is extremely important based on the operating ranges that must be produced and particularly if both production rates, moistures, percentage of recycle and other factors fluctuate dramatically. All of these must be taken into consideration for the proper application of the combustion/air system. Often, as customers convert from older style parallel flow drum mixers to more efficient counterflow designs, there is a huge surprise known as dramatic increase in dust grain loading going to the air pollution equipment. Stansteel often recommends an efficient knockout box arrangement to handle the primary dust in the off gasses of the drum mixer to “knockout” the larger particles and prevent them from carrying over to the baghouse. Then the baghouse is filtering the -200 (74 micron) size particles and even finer particulate matter. The custom design includes evaluating what is the proper air-to-cloth ratio, what is the operating range of temperatures and what has to be handled with the collected dust coming from the baghouse.

Over the last number of years, Stansteel has perfected the rugged Pulsemaster™ unit that individually pulses each row of bags in the collector. There have been experiments over the last 30 to 40 years with all types of reverse airs, plenums and other units that do not offer the effective cleaning and low pressure drop. The low pressure drop that’s experienced with the Stansteel Pulsemaster™ unit is really very environmentally conscience and very energy conscience. To maintain a lower pressure drop means there’s less resistance, in effect, the exhaust fan and motor & drive can work in a lower range and not use as much horsepower for a given measure of production. In addition, there are many critical and proven features on the unit such as:

  • Modular Design - Can set up the baghouse arrangement in extremely fast order
  • Easy bag maintenance by accessing the top of the unit and removing the snapband type bag seal
  • Heavy duty rugged tubesheet and sidewall housings
  • One piece galvanized wire cage with built in venturi
  • Superior bag airflow spacing and all bags are kept a safe distance from sidewalls
  • Top inspection doors have non-skid checker plate and industrial gasketing
  • Built in exhaust duct and custom fit inlet ducting for any type application
  • Heavy duty support structural to provide clearance for airlocks, dust blowers, vane feeders or other devices
  • Pre-piping assembly, compressed air and diaphragm valves are factory installed and aligned
  • Exhaust fan system custom sized for specific plant requirements
  • Accessible service module for housing valves, wiring and easy maintenance
  • Heavy duty screw conveyor installed in the hopper with drive
  • Bag fabric type and selection based on the application need for asphalt plants very common Nomex or Aramid appropriate fibers based on temperature range
Stansteel and our engineers and application personnel have installed air pollution systems throughout the world and understand the importance of the both the environmentally positive function as well as being a critical aspect of the production process.
