Will the WIKA Build ID replace WIKA item numbers in future?
No, the Build ID will not replace the WIKA item numbers. When you place an order, WIKA will always provide you with a WIKA item number, the standard validity of which is not limited in time.
Is it possible to dispense with a pre-filter when recovering SF6 gas with handling equipment?
Although two filter systems are installed in the WIKA handling equipment (particle filter and SF6 filter), in the event of heavily contaminated SF6, a pre-filter (e.g. GPF-10) should be used to protect the system.
