The SSH35 model is optimal for larger pumps up to approximately 400x400x650mm (WxHxD) in size such as the XDS series from Edwards, the Sogevac series from Leybold, the MS40+ and MS30+ models from Varian, and many other slightly larger laboratory pumps.
To meet different requirements, this model is available in 2 and 4 fan versions as well as IEC 10A and IEC 16A connections.
