Thermoplastic inserts from PEEK® type II reinforced with glass fibers to withstand the temperatures developing near the coil. These inserts will function as Air Flow Reducers (AFR) and they can be placed into the air holes under the coils. There is a 2 mm aperture in each AFR creating the required air pressure, suitable for MTL vaping and enhanced flavor delivery. They are available for GP® Dripper (includes two inserts), GP Spheroid V4 and GP Heron® V2 (includes one insert). The AFR for GP Spheroid V4 and the GP Heron V2 are the same with one difference. Their upper part needs to be filled down 1-2 tenths of millimeter with the help of a grit paper, protecting from shorts and it can be done in seconds very easily. Leave a note inside your order if you want AFR for Spheroid v4 and we'll do this procedure prior to shipping.
Note: * Inserts only, does not include the Dripper Base.
