The First Real
ExFog Performance Upgrade.
50% more airflow. One part swap. Bench tested.
Why It Exists
Your ExFog is capable of more than it ships with.
The ExFog and Novritsch antifog units run the same internal fan. The only meaningful difference is outlet bore diameter. Stock ExFog manifolds have a 4mm outlet - just 12.6mm² of flow area. The N-Bore Manifold Set opens that to 6mm - 28.3mm². More than double. Same unit. More air.
Bench tested across 20 filmed trials, the N-Bore upgrade delivers 50% more airflow than stock ExFog - and outperforms the Novritsch antifog unit. It is the highest-airflow manifold available for any tube-based antifog system on the market.
The Difference Is Visible
4mm stock outlet vs 6mm N-Bore outlet.
Same fan. Same power. 125% more flow area per outlet. The only thing that changed is the manifold.
