Introduction

Heldon Bi-flow filter driers offer a high level of protection for heat pump air-conditioning systems. Designed to remove moisture,
acids and solid particles that can lead to premature component failure and harmful chemical reactions.

This is achieved irrespective of refrigerant flow direction as Heldon Bi-flow filter driers have a built in check valve system ensuring all particles remain trapped once they are caught by the filter.

Standard Series ( Beige) have a solid core consisting of 100% molecular sieve. The valve plate has been designed to handle all conditions, they offer quick water absorption and are ideally suited to HFC refrigerants, POE and PAG oils.

Burnout Series (Yellow) have a solid core consisting of 48% Molecular Sieve,47% Activated Alumina and 5% Activated Carbon. They offer quick moisture and acid absorption and are ideally suited when a small motor burnout
occurs and space does not permit a full size burnout drier.
