[QUOTE="Farmer Roy, post: 5553072, member: 71668"] err, slightly off topic, but having spent my entire farming career ( 30 + years ) with airseeders of all sorts of makes & configurations, I rarely worry or consider actual fan speed, but the amount of air flowing. Generally, as a rule of thumb, the more product flowing requires more air on an 8m rig with light seeds I usually run about 3 - 4 kpa air pressure 12 m putting out say total product of 100 - 150kg/ha ( which I realise is low for you ), then I might run 5 - 7kpa. I suppose what im say is, I look more at air pressure than fan speed, which can vary across different brands or fan sizes etc . . . Of course, running D Cup style air diffusers takes away any concerns of seed bounce or blowout at higher pressures, but I find too much air can cause other issues at times, including potentially damaging delicate seeds and can significantly increase the wear & decrease life of your air hoses if worried about slot closure, have you seen some of the aftermarket closing wheels available here & in the States ?
