Capital Controls Series FX4800/4900 gas feeders are floor cabinet mounted, vacuum operated and designed to conveniently house a combination of gas feed equipment and controls. The cabinets enclose the gas flow control components and are constructed of ABS with a textured, easily maintained finish.

Easy to install for indoor installation, each Series FX4800/4900 cabinet is factory tested and needs no field adjustment prior to start-up. Eleven different flowmeter capacities ranging from 10 to 8,000 PPD (200 g/h to 150 kg/h) provide versatility in meeting gas flow requirements.

Manual Series FX4800 gas feeders consist of a cabinet, vacuum regulator and an ejector, or chemical induction unit. When automatic control is required (Series FX4900), Capital Controls' automatic valve, mounted in the cabinet responds to control signals from the CAPTROL® controller. The controller receives signals from a water flow transmitter and/or chlorine residual analyzer. If multiple feed points are required, remote meter panels and additional ejectors are provided. A switchover module is offered to provide for uninterrupted service.

Design Features
  • Modern Design: Superior materials of construction provide durability, textured finish resists fingerprints and dirt.

  • Reliable: All vacuum operation, integral venting system, double- thickness main regulating diaphragm.

  • Safe: Remote vacuum regulator mounting enhances safety of installation.

  • Versatile: Cylinder, ton container, wall or manifold vacuum regulator mounting in units up to 500 PPD (10 kg/h). Unit can be provided as manual or with automatic control. Variety of ejectors available for all applications.

  • Automatic Switchover: A separate, ndependent vacuum operated device that does not require manual reset. Each vacuum regulator has flow indication, a separate independent vent and an integral pressure relief device.

  • Technologically Advanced: The CAPTROL® controller provides microprocessor-based control, fully field configurable with gas flow output signal. The controller accepts a signal from the flow sensor and/or residual analyzer. An automatic linearized gas feeder control valve is provided for reliable control.

  • Ease of installation: Simplicity of design and modularized components minimize installation time.

  • Convenient: Controls are located at eye level and are front panel adjustable, with an easily removable front bezel for access to internal components. Saves valuable floor space in new and existing facilities.
