Stronger Spring for Apeks DS4

$45.00

In stock

SKU: TMI003 Categories: ,

This spring is stronger than the stock DS4 spring to allow first stage intermediate pressures from 14 bar (200 psi) to 20 bar (290 psi).  This allows divers to run a higher intermediate pressure for increased max depth on an mCCR.

Note: always subtract 2 ATMs from max depth calculations.

Example: (210 psi / (14.7 psi/ATM) – 2 ATM) x (33 fsw/ATM) = 405 fsw
