FAQ
What's the difference between EM-5003D and EM-5003D-N?
EM-5003D uses a 25mm/30mm adaptor plug for standard hard hat slots. EM-5003D-N is designed specifically for full-brim helmets, with an adjustable up/down and front/back mount to fit the helmet's brim shape.
Is the soft foam sealing ring replaceable?
The catalog describes the sealing rings as filled with a combination foam for optimal sealing/low pressure, but doesn't specify a replaceable-cushion program. Ask us to confirm with the factory if your buyer needs a spare-parts/replacement-cushion SKU.
