Dust & Fume Filters - Centrally DuctedCentrally Ducted Dust Collectors such as these are ideal for large shops and centrally ducted applications. Most of these solutions are based upon self-cleaning filter cleaning systems to help reduce filter costs. In addition, Water based filtration systems are available for certain explosive and flammable applications
Some important points to consider when purchasing (please do your best to answer as many of these as you can):
- What is the exact process?
- How is the emission released into the workplace?
- Does the contaminant have velocity when released from the process?
- Have you thought of any specific methods of capturing the contaminant ?
- Have you used that method of capture before? If so, did you like it or would you prefer something different.
- Are you looking at a centrally ducted system or per workstation?
- What is the Total Flow Rate? (Add up all the inlets that will run at once)
- What is the exact resistance (filter and duct losses) required for the fan to overcome?
- Do I have enough filter media (Air to cloth ratio) in the collector?
- Will it stand up to your environment (Eg: is it made from Plastic or Steel?)
- Filter cleaning: Does the filter cleaning system really work in your application?
- What will be my filter, maintenance and energy costs per year?
- Are there any tertiary risks such as fire, explosion, etc, that I need to consider?
Available with hopper and barrel (standard) or tray (low profile configuration).
This unit has been designed to be placed outside including having the top panels angled to shed water. An access panel has been added to both sides of the clean air plenum to allow for easier maintenance on the block-off components, if needed. The cabinet also has a modular design to support multiple module units (DC-36, DC-54, etc.)
The HYDROTRON is specifically designed for safe collection of potentially explosive and volatile materials and is effective in the capture of fine metal particles. It meets the National Fire Protection Association guidelines for processing and finishing aluminum. Since the Hydrotron also meets OSHA and NFPA regulations for dust removal located inside buildings, it can recirculate in-plant, tempered air to conserve energy.
The air coming through the bag is now clean, and can be recirculated within the plant or discharged outside.
1 - The fan is first activated by an "Optional" switch attached to the damper, hose reel, hose drop, current sensor*, etc. When this switch closes the fan turns on.
2 – Once the damper in the 1st drop opens, a digital pressure transmitter senses the pressure in the main duct downstream of the fan and allows the VFD to actively control motor speed as a function of duct (negative) pressure.
3 – As more dampers are opened and closed the fan speed increases and decreases in order to provide the required flowrate at each drop. This permits constant, effective exhaust at a target duct pressure no matter how many dampers are open or closed. Flow "On Demand"
4 – The fan turns off when the last operator has no more demand
