These are mounted on the system or machine FRL outlet and protect the whole downstream installation. Function is indicated with a gold coloured identification washer.
Soft Start & Pressure Decay
These LF3000 Series fittings allow air pressure to gradually increase when a compressed air line is restarted after venting.
When downstream pressure equals 2/3 of the supply pressure, full flow is automatically established Fully adjustable to optimise air line pressurisation time Soft start prevents shocks to system components which can occur when full working pressure is immediately introduced
