QS SPIROMATIC
FACE MASK WITH BREATHING VALVE

SPIROMATIC FACE MASK is comfortable and reliable, designed with Interspiros outstanding safety pedigree and innovative approach. The inner mask separates inhaled and exhaled air to minimize the danger of breathing exhaled carbon dioxide.

SPIROMATIC BREATHING VALVE is a positive pressure valve equipped with a bayonet connection to the face mask. The design of the demand valve supplies air only while inhaling, with instantaneous response to workload differences. Positive pressure is automatically activated on first breath. Breathing apparatus from Interspiro is an investment with a long service life, when properly maintained. To simplify service and to obtain maximum product performance we recommend using our service kits, containing original spare parts necessary for preventive maintenance. Interspiro offers training courses for users who perform day-to-day service work, as well as training for service personnel performing full maintenance programmes.
