Abstract
The present invention relates to flow control devices (4) for use with cartridge filter cleaning systems. The flow control device (4) includes a cylindrical portion (8) which extends away from a conical portion (6). When the device (4) is used with a nozzle (9) attached to a blow tube (13) the device (4) will uniformly clean a dirty cartridge filter (5). The advantage of the invention is that the device (4) can be used in the current range of air flow rates and nozzle sizes that are used in the cartridge cleaning industry. Whereas the prior art systems (7) show deficient performance when used across the full range of air flow rates currently applicable in industry.
