Where to use

  • icon General Information

    The Pro-Ap® is the only hose-end liquid siphoning applicator specially designed for golf, sports turf and professional landscape applications. This unique applicator uses a shower type nozzle that provides a gentle spray while ensuring uniform coverage. The Pro-Ap is the only adjustable applicator that can apply small quantities of product at high water pressure and flow rates with a metering dial that offers 10 additive settings, including water only.

    The Pro-Ap Applicator operates on water pressure. Water flowing over a small orifice creates a suction that lifts and mixes the active ingredient additive into the spray stream. The applicator design allows for small quantities of liquid product to be applied with large volumes of water.

    Fill the Pro-Ap bottle with the desired volume of liquid solution that is to be applied to an individual turf area (32 fluid ounces maximum). Secure the bottle into the siphon-metering cap inside the applicator.

    The Pro-Ap adjustable metering dial offers 10 additive settings, including water only. Refer to the Pro-Ap operating instructions for more details regarding use of this hose-end, liquid siphoning applicator.

    Remove the Pro-Ap bottle and secure its contents with the bottle cap after use. Always operate, transport, and store the Pro-Ap in the upright position when bottles are attached.
