Operation and Safety Specifications for Portable Sandblaster Tank
1. Brief Profile
The Portable Sandblaster Tank is a compact, mobile abrasive blasting system designed for surface preparation, cleaning, and finishing across diverse industries. Engineered with corrosion-resistant materials (e.g., steel or stainless steel) and equipped with pneumatic pressure control, this unit operates by propelling abrasive media (e.g., sand, steel grit, glass beads) through a nozzle using compressed air. Its portable design—featuring wheels, ergonomic handles, and lightweight construction—makes it ideal for on-site applications in construction, automotive, marine, and manufacturing sectors.
Safety is a core priority, with built-in features such as pressure relief valves, deadman handles, and moisture separators to mitigate risks of over-pressurization, accidental activation, and equipment damage. Compliance with OSHA, ASME, and CE standards ensures adherence to global workplace safety protocols.
This system is favored for its ease of use, cost-efficiency, and adaptability to small-to-medium-scale projects, offering a practical alternative to stationary sandblasting cabinets.

Removes weld slag and surface imperfections.
Art & Restoration:
Cleans sculptures, historical artifacts, and architectural details without damaging delicate surfaces.
Food & Pharmaceutical Processing:
Sanitizes stainless steel tanks, reactors, and piping by removing residue and contaminants (hygienic models available).
The tank’s adjustable pressure and abrasive flow enable it to handle soft materials (e.g., wood, aluminum) and hard metals (e.g., steel, iron) with equal precision.
3. Features
