    Looking at this pic of a 4" RVK...



    It would appear that yours is the wrong way around?

    Check the arrows to see the direction of air flow

    I had a 5inch in that size tent an it was very strong pull so you should get a good amount of negative
    Pressure with that fan.if air is blowing from the duct then it's the right way round.
    If it is then take the filter cover off that will make it suck freely....oioi
