Introduction
The OptiFlo DustCatcher by AAF International is a compact, efficient dust and fume collector designed to meet stringent air quality standards. It is engineered to improve industrial air quality by capturing sub-micron particulates, allowing for cleaner air recirculation and reduced energy costs.

Specifications and Features
The DustCatcher is available in three sizes suitable for small to medium dust volumes. It includes an enclosed fan with a built-in silencer, self-cleaning cartridge filters, a wired control panel, and a quick-connect dust disposal pail. Constructed from 12-gauge welded steel, it is designed to withstand pulse-jet cleaning stress. Optional features include an explosion vent, HEPA afterfilters, and a 55-gallon drum adapter.

Operation
Dust-laden air enters through one of four inlets, moving downwards through cartridge filters. An internal baffle directs heavier dust into the collection hopper, while lighter particles are captured on filter surfaces. Clean air exits through the outlet. Filters are cleaned with timed pulses of compressed air, dislodging dust into the hopper for easy removal.

Unique Filtration Design
The DustCatcher employs a downflow air principle with an open cartridge filter section to prevent dust re-entrainment during cleaning. The tamper-proof cartridge filter seal prevents leakage and dirty air bypass. Quick-release latches facilitate fast filter changes.

Efficiency and Certification
DuraKlean filters, standard on DustCatcher units, are certified for high efficiency, achieving 99.999% efficiency on 0.8 micron particles, as per RP-531 test procedures.

Noise Reduction
The DustCatcher features a built-in silencer for quiet operation. The fan and motor are enclosed, with sound-absorbing material lining the interior to minimize noise and vibration.

Control System
The control system is prewired in a NEMA 4 enclosure, featuring UL or CSA approved components. It includes an adjustable solid-state timer for cleaning system initiation and a pressure gauge for monitoring filter pressure drop. Remote start/stop capability is included.

Dust Disposal
A heavy-duty, snap-in-place five-gallon container facilitates easy dust disposal. Located outside the collector, it reduces the risk of dust re-entrainment.

Applications
The DustCatcher is suitable for various applications, including pharmaceutical, woodworking, metalworking, and other industrial processes such as chemical handling, food processing, and paint pigment management.
