air control assembly brushed nickel metal 2Using the Air Control, the bather can easily adjust the amount of water pressure with the turn of the cap. The air control cap features a window which reveals a minimum and maximum setting. Air is drawn from under the deck for extremely quiet operation. The Air Control has a smooth, lo-profile look.

Silent (Standard) Air Flow Control Valve

This Silent Air Flow Control allows the bather to adjust the amount of air volume via a “Minimum – Maximum” air flow adjustment range, and the plastic caps shown below feature a visual adjustment “window” to visually note the air flow setting. Air is drawn from under the deck for extremely quiet operation – so this Air Flow Control is often referred to as the “Silent” Air Flow Control. The Air Control has a smooth, lo-profile look. Note: The metal caps do not include this notched window.This Silent Air Flow Control Assembly should NOT be installed within the bathtub bowl, since it should not suck water into the air flow control assembly.

Gruber also manufacturers Sealed Air Flow Control Valves that are imperious to water exposure, and can be used within the bathtub bowl. Note: The Air Control and Pneumatic Controls are universal for all Jet series.

Sealed Air Control Cap (without Window)

Like the Silent Air Flow Control, this Sealed Air Flow Control allows the bather to adjust the amount of air volume via a “Minimum – Maximum” air flow adjustment range. Since this Air Flow Control is sealed, it may be installed inside the bathtub “bowl” and may be exposed to or covered by water. The water will not leak past and go behind the bathtub. The Air Control has a smooth, lo-profile look.
Marshall Gruber also manufactures a Silent Air Flow Control Valve that features a notched “window” in the cap to observe the Min/Max Air Flow setting that is integrated into the body. The Silent Air Flow Control cannot be placed within the bathtub bowl or placed in a manner where water can be sucked into the control.
