I am really excited to introduce our new HS40 'Compact' Bubbler.   Meticulously engineered
to deliver reliable, trouble-free operation, year after year, even in the harshest possible environments.  No moisture issues or desiccant to recharge means greater reliability, a reduction in unscheduled site visits and cost savings overall. The new HS40 Compact incorporates the most valued features of earlier models whilst setting a whole new standard in performance and price.
