Frequently Asked Questions
Who is CleanSpace CST ULTRA suitable for?
CleanSpace CST ULTRA is designed for professional work environments with respiratory risks, such as welding, metalworking, construction, concrete cutting, mining, manufacturing, recycling, and decontamination.
Does CleanSpace CST ULTRA use a hose or waist unit?
No. Because the power unit is located behind the mask, it doesn’t require the long air hoses and waistband found in traditional PAPR systems.
How long does CleanSpace CST ULTRA last?
The system can offer up to 14 hours of battery life depending on operating conditions. Filter type, filter saturation level, operating intensity, and mask sealing may affect the actual duration.
Which masks can be used with CleanSpace CST ULTRA?
CleanSpace CST ULTRA can be used with compatible CleanSpace CST half-face and full-face masks. The appropriate mask size should be determined by a mask fit test performed on the user.
Can CleanSpace CST ULTRA be used against gases and vapors?
When the appropriate particle and chemical filters are selected, they can be used in specific gas and vapor applications. Filter selection should be based on the type and concentration of the pollutant.
Does CleanSpace CST ULTRA provide oxygen?
No. CleanSpace CST ULTRA filters ambient air; it does not produce or supply oxygen. It should not be used in oxygen-deficient, oxygen-rich, or directly hazardous environments.
