How to wire and size a potential relay
To size a potential relay you must read the Start winding voltage (the BEMF)which will be above the supplied line voltage, in this example I use 300 volts for math.BEMF = 300 volts,300v x ,50 = 150v minimum300v x .80 = 240v maximum300v x 1.20 = 360v continuousSo you want the Start capacitor to stay in the circuit to at least 150v BEMF or risk stalling, and you do not want the Star capacitor to stay in beyond 240v BEMF or riskexploding the Start capacitor.The 120% continuous rating is to oversize the coil in the potential relay that remains in the system to protect it .If you have a compressor that is not running you will need to jump it with a Start capacitor(a large one) to the run capacitor for 1 second or so to bump start the compressor, then you can read the Start winding for the BEMF reading.
I need a head valve seat for central pneumatic 21 degree angle framing nailer model 60828 also need headvalve seat for 34 degree angle finish nailer 68020
I have not been able to purchase replacement parts for these nail guns , however, have repaired them using parts from Bostitch framers and or just make the part. If the seal fits over the top of the cylinder, then try using seal from Bostitch framer part #N70155 fits a bit tight but works. Heat with a hair dryer to soften and install. If the seat is incorporated within the head valve, just dig it out and replace it with liquid two part urethane. Just mix and pour it in. After cleaning out the old seal, place head valve on level surface and pour in the mixed urethane till slightly over full to give the seal a nice crown. The finish nailer might also be repaired using other brand of seals. Remove the old part and take it to service center for a possible match. Good luck with your repair.
What oil should I use in Handiair H8/25 Compressor?
Many air compressors use a mineral blend or a synthetic oil, such as synthetic hydrocarbon, polyol ester or polyglycol. It is important to use a lubricant specifically rated for air compressors; do not use a general-purpose motor oil used for automotive or other purposes.
