Wall mounted bulk fill dispenser for instant foaming hand soap.
20ml foam shot (0.6ml liquid).
Bulk soap dispensers are more cost effective than the pouch or cartridge refil type. They can can be refilled or topped up at any time ensuring you never run out.
The cartridge type has a specially made refill that are much more expensive per litre than bulk fill soap. They are sealed and therfore cannot be topped up. The cartridge has to run out before it can be changed. In some cases you can replace a partly used cartridge out before it is empty but this also adds to the running cost
