3M™ Versaflo™ S-Series Hoods and Headcovers3M™ Versaflo™ S-Series Hoodsand Headcovers for Powered andSupplied Air Respirators/Versaflo22Many wearers of half and full facepiece respirators are taking a second look at powered and supplied air respirators for reasons that go beyond compliance.All-Day ComfortNew 3M™ Versaflo™ S-Series Hoods and Headcovers have beendesigned to provide users with the optimal level of comfort.Easily adjustable suspensions (most models) and soft comfortpads help provide excellent fit, stability and tracking. Comfortsuspension hoods and headcovers feature wide faceseals withsoft elastic for improved comfort and reduced air flow noise. Thepremium reusable suspension allows wearers to modify the airflowdistribution inside the hood to suit personal comfort needs. All ofthese improvements combine to help workers stay more comfortablethroughout the day.VersatilityAs a part of Versaflo respirator systems, S-Series hoods andheadcovers can be used in dozens of different Powered Air PurifyingRespirator and Supplied Air Respirator combinations.Excellent AirflowS-Series hoods and headcovers direct a comfortable stream of airinto the headgear. The moving airflow may make hot environmentsmore tolerable while reducing visor fogging. When used with anapproved 3M™ Supplied Air Regulator, the compressed air can bemade cooler or warmer by up to 50°F (28°C) for additional comfort.High Performance–APF3M has conducted research to document an Assigned ProtectionFactor (APF) of 1000 for the S-Series hoods when used as part of aNIOSH-approved powered or supplied air respirator system. An APFof 1000 is the highest level allowed under the Occupational Safetyand Health Administration (OSHA) Respiratory Protection Standard(29 CFR 1910.134) for this class of respirator. S-Series headcovershave an APF of 25, making them suitable for a wide range ofapplications and working environments.Fast AssemblyAll S-Series compatible breathing tubes feature the innovative 3M™Quick Release Swivel (QRS) connection. Simply push the QRS end ofthe breathing tube into the air inlet of the headgear until it snaps intoplace. The breathing tube can be quickly removed with only one handby squeezing the breathing tube clips.Simple MaintenanceChoose the ready-to-use integrated suspension models forapplications where assembly would be too time-consuming orimpractical. Or select the premium reusable suspension hoods forquick, highly cost-effective replacement of outer fabrics.3M™ Versaflo™3M ™Versaflo ™4Integrated Suspension Hoods and HeadcoversAvailable with two different suspensions, comfort and fabric,integrated suspension hoods and headcovers offer the advantage of being fully assembled and ready to use straight out of the box. They can be suitable for applications that require frequent replacement of the entire headgear assembly, such as pharmaceuticalmanufacturing, or in situations where there is less soiling of the outer fabric. Integrated suspension headgear is available in two sizes to comfortably fit more wearers: S/M and M/L.CoMFoRT SuSPENSIoN MoDELSIntegrated suspension models S-133, S-133B and S-533 also feature a wide faceseal with soft elastic for improved comfort and reduced noise. The new airflow distribution minimizes the potential for air whistling past the wearer’s ears, allowing for better worker communication and improved comfort.

However, the PTV with Bruker’s “backflush” technique can reliably divert the higher boiling sample matrix away from the column. The benefits of this accessory are many:Run more samples per day - decrease analysis times as the heavy components are quickly eliminatedSave time by eliminating column bake out Preserve column performance for extended period of time ChromatoProbe™Added Versatility for Superior Analysis of Solids, Liquids, and Slurries. Compounds such as street drugs, industrial solids, synthetic organic products, and plant tissues that normally are not considered amenable to GC-MS analysis can be easily investigated with the ChromatoProbe. Samples are introduced into the PTV injector via disposable micro-vials.Non-volatile or thermally degraded components from the sample remain in the micro-vial allowing the system to remain clean.ChromatoProbe Benefits:Increase uptimeMinimize system contamination with disposable micro-vials and split injectionsDirectly desorb samples in the PTVinjector without added hardware(unique Direct Sampling Capability)B r u k e r D a l t o n i c s i s c o n t i n u a l l y i m p r o v i n g i t s p r o d u c t s a n d r e s e r v e s t h e r i g h tt o c h a n g e s p e c i f i c a t i o n s w i t h o u t n o t i c e . © B D A L 04-2015, 1836727For research use only.
