Built-in with both Pulse Width Modulation (PWM) and speed controls, PRE-T-COOL pre-treater is able to output at precise density, from as low as 15g to 25g per A3-area (14″x17″) with five levels to choose from.
You might need 15g per A3 for light-coloured t-shirt pre-treatment and 20g per A3 for dark-coloured t-shirt pretreatment. Every function is just a toggle of a button!
