I have purchased a heavy duty compressor from Maplins. Its rated up to 140psi which should be ample for our launches since we rarely go above 100psi. But more importantly it is rated for 15 minutes continuous use at that pressure and even longer at lower pressures.
This is very important for launching water rockets as most compressors seem to burn out trying to pressurise larger rockets, I’m hoping this heavy duty one will be more suitable.
Once the weather starts to warm up next year I will test it out.
