Replacement booster flap
This replacement booster flap is designed to seal the vacuum chamber manifold inlet when a vacuum booster box is not installed, helping maintain optimal vacuum performance. Suitable for portable machines manufactured by Steamvac, Powerforce, Razorback, and Kanga.
What it seals and why
The flap closes off the vacuum chamber manifold inlet when no booster box is fitted. With it missing or perished, the machine draws air through the open inlet instead of through the hose — which is a direct loss of lift at the wand, all day, with nothing to see.
If a portable has quietly lost recovery and the hoses and cuffs check out, look inside for the flap.
Tell us the machine or tool and we will confirm the part before you order.
