Nitrogen is an inert gas that does not burnor explode and is not poisonous. Pleasenote!: the internal pressureof gasspringscanbeup to 4,351psi.Donot attempt toopenormodify them. ACEgas springswill operate in surrounding temperatures from -4 °F to 176 °F.We canequipour springswith special seals towithstand temperatures as low as -49 °For as high as392 °F . Gas springs should not beplacedover heat or inopen fire! Disposal/Recycling: GasSprings consistmostly ofmetal and the metal couldbe recycled, but first thegas pressuremust be removed. Please ask for our disposal recommendationswhich advisehow to depressurize thegas springs andmake them safe to recycle. All gas springs aremarkedwith thepart number, theproductiondate and awarning sign “Donot openhighpressure”.We arenot responsible for any damages of any kind that arises due togoods that arenot marked accordingly. Gas springs shouldbe installedwith thepiston roddown. This position ensuresbest dampingquality. ACEgassprings includean integrat- edgreasechamberwhichallows for alternativemounting opportunities. Gas springs shouldnot beexposed todynamicor static side load forces. This can causebendingof thepiston rodpremature failure. Toobtain theoptimumoperation for agas spring it is important to identify the following points: • gas spring size • requiredgas spring stroke • mountingpoints on flap and frame • extended lengthof thegas spring • requiredextension force • hand forces throughout the complete movement on the flap Withour freecalculationservice you can eliminate the time-consuming calculations. Please sendus your detailsby fax or e-mail. Just complete the information shownon the calculation formulapagenumber 121. Please attach a sketchof your application (a simple hand sketch is sufficient) in side view. Our applicationengineerswill determine the optimumgas springs andmountingpoints to satisfy your requirements. Youwill receive aquotation showing theopen- ing and closing forces andour recommended mountingpoints to suit your application. IndustrialGasSprings Calculation andSafety Instructions Gas springs aremaintenance-free. Donot greaseor oil thepiston rod. Thepiston rodmust not bepainted and shouldbeprotected against shocks, scratches anddirt. The cylinder shouldnot bedeformed as such damagewoulddestroy the sealing system. ACEgas springs canbe stored in any position. Pressure lost through long storage is not tobeexpected. There areno knownnegative values, but theremay be a stickingeffect the first time you compress a spring. Thismay require ahigher initial force tooperate thegas spring for the first time (initial breakaway force). Gas springs of all sizes are classified as pressure vessels according to thepressuredevicedirective97/23/EC. They have apressure level of more than7.25psi bar. All ACEgas springs aredeveloped,manufac- tured and tested according to this directive. The tolerance for the installation length is generally deemed tobe ± .08". If very highdemands areplacedondurability and stability, please avoid the combinationof small diameter + long stroke+high force. The filling tolerance: ±7%. “Calculationoffer with all requireddetails for assembly!”
