Need help?Do you have a question about the Air Quality Engineering MistBuster 500 and is the answer not in the manual?
The MistBuster® series of air cleaners, including models 500, 850C, 850, and 2000, are designed to provide clean air in industrial and commercial environments by filtering mist and smoke generated from metal machining applications. These CE Compliant units are machine-mountable and are protected by U.S. Patent Numbers 6,428,611 and 7,717,984, reflecting their advanced design and functionality.
The primary function of the MistBuster® is to capture and filter airborne contaminants such as mist and smoke produced during metal machining processes. This is achieved through a multi-stage filtration system that ensures high efficiency in removing submicron particles. The units are equipped with a motorized impeller, which is a backward-curved, vibration-free, direct-drive component responsible for drawing contaminated air into the system.
The filtration process begins with the first stage, which utilizes a 4-inch aluminum mesh impinger. This initial stage is designed to capture larger droplets and particles, preventing them from reaching subsequent filtration stages and extending the life of the more delicate components. Following this, the air passes through the second stage, which incorporates an AQE Advantage™ (Long Life) Electronic Cell. This electronic cell is crucial for electrostatically charging and collecting smaller particles. For the MB850C and MB850 models, the filtration continues with a third stage, the MistBuster (High Efficiency) Cell, and for the MB850, an optional fourth stage, another MistBuster (High Efficiency) Cell, further enhances particle removal. The MB2000 model extends this with a third and fourth MistBuster (High Efficiency) Cell.
An optional final stage is available across the series, offering flexibility based on specific air quality requirements. This stage can be a HEPA filter, providing 99.97% efficiency for submicron particles, an ESF Filter, or a Carbon Module, which is particularly effective for odor control. The electronic cells are powered by a self-regulating, dual-voltage, solid-state power supply, with two such supplies for the MB850 models, ensuring consistent performance. The overall efficiency of the MistBuster® units is up to 99.9% on submicron particles, adhering to ASHRAE 52.2 standards.
The collected fluids from the machining processes drain directly back into the machine tool through the inlet opening. This design feature is beneficial as it helps to keep the impingers and electronic cell cleaner by continuously flushing them with the collected fluid, reducing the frequency of manual cleaning.
The MistBuster® units are designed for ease of use and integration into commercial and industrial settings. They are machine-mountable, allowing for direct attachment to machining equipment, which optimizes the capture of mist and smoke at the source. Each unit comes with a 10-foot power cord equipped with a standard molded plug, facilitating straightforward electrical connection to a grounded outlet. For permanent installations, the MistBuster® can also be hard-wired, with all wiring needing to comply with applicable codes and regulations. Proper grounding is emphasized as essential for both safety and optimal operation.
Operation is initiated by rotating a control knob clockwise to set the desired airflow. The manual recommends setting the airflow at the minimum level that maintains proper negative pressure, often achievable at the three o'clock setting on the speed controller. This approach helps reduce noise, minimize maintenance, and increase overall efficiency. A performance indicator light confirms that the blower is running.
A test button is provided on the front of the unit to momentarily short out the collector on the electronic cells. Arcing observed during this test indicates that the cells are properly energized. Furthermore, a toggle switch on the front of the MistBuster® allows for compensation of nuisance arcing, which can occur with certain water-soluble or synthetic fluids. Users can switch to "oil mode" for higher voltage operation or "water mode" if nuisance arcing becomes an issue, providing adaptability to different machining fluid types.
Routine maintenance is crucial for the continued high performance and longevity of the MistBuster® units. The main components requiring periodic cleaning are the mist impingers and the electronic cell. The exact cleaning interval varies depending on the application, with water-soluble and synthetic machining fluids typically requiring more frequent cleaning than petroleum-based fluids. Users are advised to inspect these components during the first few months of operation to establish an appropriate cleaning schedule.
When cleaning the electronic cell, extreme caution is advised due to the sharp edges of the collector plates and ionizing wires. Users are instructed to wear appropriate protective gear, including goggles and gloves, and to avoid skin contact with alkaline detergent solutions. The electronic cell must also be handled with care to prevent damage.
Cleaning can be performed using a parts washer, provided the cleaning fluid is aluminum-safe and the pressure does not exceed 60 psi [414kPa]. For manual cleaning of the mist impingers, they should be soaked in a solution of hot water and alkaline detergent for 10-15 minutes, followed by thorough rinsing with hot water to remove any residual detergent.
Manual cleaning of the electronic cell involves immersing it in a wash tub filled with cell cleaning detergent and hot water for five minutes, according to the detergent manufacturer's instructions. After soaking, the cell must be thoroughly rinsed with very hot water to ensure no residue remains. Users should inspect the collector plates for cleanliness and repeat the wash procedure if necessary. It is also important to check for broken wires and bent collector plates. After cleaning, the cell can be reinstalled, though the indicator light may remain off for up to two hours during the drying time.
For applications using water-soluble machining fluids, it is recommended to coat the cleaned cell with AQE Cell Coat after washing. This helps to protect the cell and maintain its efficiency. The manual directs users to the Parts List section for specific part numbers for the detergent and cell coat, ensuring that the correct maintenance products are used.
The MistBuster® series is designed with a focus on durability, featuring a 16-gauge steel cabinet with a chemical-resistant baked enamel, textured finish, providing robust protection in demanding industrial environments. The ingress protection rating of IP 20, according to IEC 60529, further indicates its resistance to solid objects and some protection against water. Manufacturing dates can be identified from the first four digits of the serial number, allowing for precise tracking and service.
