  • GFRC Spray Guns

    Sprayer RPN forms a flow of cement, sand and fiber, which is sprayed using compressed air. Fiber is distributed evenly in the solution.

    The gun consists of two parts: Chopper and Mixer.

    • Chopper cuts and feeds fiber.
    • Mixer is a spray head. Mixer sprays the solution and mixes it with the fiber.

    Chopper and mixer can be used separately. Chopper separately cuts the fiber for the premix. Mixer is used separately only when applying front layer onto a mould.

    Sprayer RPN-6

    NEW 2020: innovated model of GFRC chopper gun.

    There are a number of upgrades that make this gun more comfortable and attractive for those professionals, who use the spray method much and often on the products of different scale and surface relief.

    Advantages of RPN-6 over RPN-5:

    1. New sealing of D-shaped section of the chopper cover.

    It has a higher tearing strength ensured by 3 contact points when glued to the cover body frame. 

    Enhanced sealing of the inner cavity.

    A body frame of the chopper and its cover has an interlock connection, sealed with a D-shaped section (the middle part of the cover penetrates the inner cavity of the body frame).

    2. Changing the pattern width of the sprayed slurry is carried out by replacing the external nozzle, the end of the PNS 04-02.00.07 tube has a groove-free smooth cone surface.

    It is worth reminding that 3 options of tube are available for RPN-5: straight, skewed and semi-skewed.
    3 types of external nozzles are available for RPN-6 model:

    • 0° groove angle - to form a narrow focused spraying pattern (supplied on request);
    • 8° groove angle - to form a medium wide spraying pattern;
    • 16° groove angle - to form a large width spraying pattern.

    Spray angle options
    Spray angle options

    It is now possible to change the width of the spraying pattern very quickly by replacing only the external nozzle without mixer rinsing, i.e. during operation.

    Increased sustainability of external nozzle slots, as they are made of wear-resistant polyurethane elastomers.

    3. The end part of the mixer internal nozzle is rubberized with polyurethane elastomers. These are 2 nozzle options: with or without a knob. The end parts of these nozzles are always subject to wear as they are in continuous contact with shotcrete.

    Now these nozzles will have to be changed less frequently, as polyurethane will wear out less and longer from the contact with cement and sand solution.

    4. Center bore of the fixing cover (cover PNS.04-02.00.05) of mixer has a diameter of 38 mm due to the increased diameter of the external nozzle. The diameter for RPN-5 model is 34.5 mm. Yes, the difference is only 3.5 mm, but clogging now is less like happening.

    Upon request, we will send a link to the scheme of the gun and all parts of which it consists. Use the same link for pricing and spare parts order.

    Please consider tube option PNS 04-02.00.07 (ПНС 04-02.00.07) installed inside the mixer. It forms the surface of the outer circumference of the annular gap, through which the cementitious slurry follows.

    Three options:

    • Tube with straight slots. Sharp outline spot. Application to small moulds of complex geometry and with the pump of low-capacity.
    • Tube with skewed slots. Blured (soft) spot without sharp contour along the perimeter. Application to big moulds and with the pump of high-capacity.
    • Tube with semi-skewed slots. Smoothed spot with smooth and various contour along the perimeter. Universal. Used in a wide range of pump capacity.

    As of September 01, 2019, all RPN-5 guns are equipped only with a tube with semi-skewed slots. Tubes with straight and skewed slots are available on request.

    Air-powered drive is lubricated automatically when using RPN-5 Gun with NST pumping station.
