Which protection class do the JDN Air Hoists have?

On electric equipment the compartment or case is classified according to IP or NEMA. For example IP 68 means a housing safe against dust ingress and submersible for a certain time according to manufacturing specifications.
Air Hoists are an open system which is by nature sturdy and insensitive against dirty, aggressive and humid environments. The supply air blows out any ingress. So this makes the air hoist a unique and reliable tool in harsh environments and incomparable to electric hoists.
