Comparison of Pneumatic, Electric and Hydraulic Sprayer Performance
Pneumatic sprayer's working pressure is medium (3-8MPa), pressure stability is general, power from compressed air (need air compressor), material adaptability with low - medium viscosity coatings (such as latex paint, ordinary paint), high viscosity materials easy to clog the gun, durability of the structure of the simple but wear parts (such as seals) life is short, rely on the cleanliness of the air source, the maintenance cost of the pneumatic sprayer is relatively low, more Suitable for decoration in the coating, furniture local painting, small and medium-sized industrial parts spraying.
Electric sprayer working pressure is low (1-5MPa), pressure is easily affected by voltage/load, power comes from electric motor (220V/380V), material adaptability is only suitable for low viscosity coatings (e.g. waterborne paints, varnishes), unable to deal with high viscosity putty/thick slurry paints, durability motor/piston pump is easy to wear and tear, long term high-frequency use of high failure rate, life expectancy 2-3 years, maintenance costs Medium (motor/circuit maintenance), suitable for home DIY, wall repair, furniture refinishing, small batch crafts painting.
Hydraulic sprayer with high working pressure (20-30MPa), stable and adjustable pressure, powered by hydraulic pump (diesel/motor-driven), high material adaptability, can handle low - high viscosity materials (from varnish to fireproof paint, epoxy flooring paint), high strength of the hydraulic parts (pump body, cylinder), wear-resistant, life expectancy of 5-8 years under normal maintenance, with high maintenance costs (hydraulic High strength of hydraulic parts (pump body, cylinder), abrasion resistance, 5-8 years of life under normal maintenance, high maintenance cost (hydraulic seals/oil replacement), suitable for large-area spraying on building facades/roofs, industrial anti-corrosion (tanks/pipes), and thick-coating (fire protection/insulation paint).
Summarize:, pneumatic sprayer is the "cost-effective choice", electric sprayer is the "lightweight entry choice", hydraulic sprayer is the "professional and efficient choice", the positioning of the three clearly, respectively, match the construction scenarios of different sizes and needs.
