• External Filter Housing
Clear External filter housing allows an
immediate visual inspection of filter’s
condition.
• Flow Fault & Test Indicators
Flow Fault indicator lights up if unit
operates outside ± 5% of set flow rate.
Battery Test indicator lights up when
battery can provide a minimum of 8
hours of operation over operating
range.
