The MB 15 ST. DR. hand held Eyebath / Face Wash Fountain suitable for (tropical) outdoor use, resistant to high temperatures (solar radiation) by means of the self draining principle. This model has a 1¼” or 1" BSP standpipe and floor mounting plate. Standard we have a bottom water inlet, but this can be changed to any position you require, in case we install a 3 - way valve (model MB 350 series). The Eyebath has dust covers on the diffusers, optional supplemented with black rubber Eye cups with hinged dust covers (including sign). These diffusers give a gentle aerated soft spray pattern which feels pleasant for the eyes. Operation standard by means of foot treadle, but optional possible with panel type foot control. The dust covers need to be placed back on the diffusers after usage. Also a Flow regulator is present on the unit in order to achieve a good spraying pattern. The MB15 can have a single sprayer / diffuser or a double (two) diffusers. The standpipe and Eyebath are draining completely empty after usage this will prevent unacceptable temperature in the standpipe by solar heating. Minimum water pressure is 2 bar.
