FR301A Pneumatic Gravity Feed Hopper Sprayer for Heavy Viscosity Wall Finishing

The FR301A is an enhanced iteration of hopper style pneumatic sprayer, optimized for heavier bodied construction coatings. This upgraded unit carries a reinforced 5000cc translucent polypropylene reservoir, strengthened internal fluid passage plus 4/6/8/10 mm four piece hardened metal orifice set. Improved flow channel design reduces clog risks when spraying dense putty, heavy stucco and thick diluted mortar. Its quick detach hopper structure accelerates post shift cleaning and daily tool maintenance for continuous construction site work.

Reinforced 5000cc Translucent PP Material Reservoir

High impact modified polypropylene hopper with ergonomic side grip. Transparent body allows operators to observe residual coating volume at a glance. Reinforced threaded joint prevents leakage under high flow working conditions; quick release mounting supports fast disassembly for full flushing.

Four Piece Hardened Metal Orifice Kit (4/6/8/10 mm)

Upgraded hardened metal orifices extend service life when spraying abrasive granular materials. Four aperture sizes handle materials ranging from fine interior filler up to coarse heavy grained stucco mixes. The extra large 10 mm orifice is built for high viscosity, particle loaded building compounds.

Reinforced Heavy Duty Gun Core Assembly

Optimized internal flow path lowers material blockage probability. Optimized trigger geometry and non slip grip ease fatigue during long hour overhead ceiling spraying. Dual adjustment knobs independently regulate airflow and material output for precise texture control.

Broad Range Air Compressor Compatibility

Standard G1/4 inch air inlet port. Redesigned internal air circuit delivers stable air output across fluctuating compressor supply, adapting to various field site pneumatic setups.

FR301A gravity feed texture sprayer is the upgraded contractor focused variant derived from FR301 model. Compared with base FR301, it expands orifice selection to four sizes, adopts impact resistant reinforced hopper and optimizes internal fluid pathways for thicker, abrasive building coatings. This tool fits professional painters, medium to large renovation crews and subcontractors for interior exterior wall texture, heavy grade putty, stucco and thick mortar spraying. Complete kit contains spray gun main unit, 5000cc PP hopper, four hardened metal orifices and printed operation guide for immediate deployment.

What kinds of coatings is FR301A suitable for?

This upgraded hopper sprayer works for common wall filler, decorative stucco, high density heavy grade putty and thick diluted mortar with fine to medium particles. Not fit for concrete containing oversized coarse aggregates.

What capacity does the reinforced PP hopper hold?

Equipped with 5000cc impact resistant translucent gravity feed hopper, users can check remaining coating volume directly during work.

What pressure setting should operators adopt?

Recommended operating pressure:4.5-8.5 Bar (65-120 PSI). Modify pressure according to coating thickness for ideal spraying performance.

Does FR301A resist frequent clogging?

Redesigned anti clog internal flow path greatly reduces blockage probability. Still fully detach and rinse hopper and orifice parts right after finishing work to avoid material curing.

What orifice components come with FR301A package?

Four hardened metal interchangeable orifices:4.0 mm, 6.0 mm, 8.0 mm,10.0 mm. Match orifice dimension based on coating viscosity and particle size.
