Pool tile cleaning machines are portable blast machines in 0.5 or 1 cubic feet in media capacity, these are typically used to remove calcium and mineral deposits off of pool tile or water features. These machines allow pool service companies to blast with kieserite, crushed glass and glass bead with excellent production these machine are typically fitted with No.2 or No.3 size nozzles allowing the use of smaller air compressors if needed. Pool tile cleaning machines allow easy transport of equipment due to there small size. If kieserite is used for blasting the material may harden within the pressure vessel if it is left for a long period of time. All models offered have an inspection door that allows operators to clean the internals of the pressure vessel, unlike most mass produced small pressure vessels. Having equipment with remote controls apposed to manual or ball valve controls provides far higher material economy and blast operator safety. These machines can provide top quality results and excellent material economy if operated and maintained properly.
