FAQ

Q2.  What kind of battery are they?
A2.  The batteries are sealed lead acid which do not have memory effect and can be charged and recharged anytime.  Commonly used in Motorcycles or scooters and golf carts.  
Q3.  How long do the batteries last?
A3.  As in most batteries, run time is a function of how much power stored and the amount of power needed or draw.  The standard battery we ship with most bunkers is 7 amp hours (7AH).  This battery will keep the bunker inflated for 9 to 12 hours depending on many things such as environmental conditions, age of the battery and so on.  If one needs more run time, batteries with more AH are available.  Such as 9AH, 12AH, 18AH and so on.
  Q4.  How do you recharge batteries?
A4.  Supplied wall chargers trickle charge the batteries overnight.  Chargers draw very little power and are commonly placed on power bars for nightly charging.  Charged batteries are connected and bunkers inflated.  See the video below for an example of bunker inflation without remote controls.

Q11.  How do the bunkers “Pay for themselves”?
A11.  Most of us field owners pay for labor to set up the bunkers.  Or if we are doing it ourselves or with family, there is a cost to your business while you are spending time inflating bunkers.  The way the bunkers pay for themselves is simple math.  

1. On average it takes 2 employees an hour each with two blowers to inflate 48 bunkers.  This is two labor hours.  The reason is that each employee must stand behind each bunker holding the blower while they inflate, cap it and then finally move to a second bunker.  With Vortex Bunkers you simply attach the battery, seal the velcro door and move on to the next while it self inflates.  With the remote system, batteries will turn on with a push of a button.  So lets just say it takes our two employees 15 minutes for 48 bunkers.  The labor savings is 2 hours – .5 hour or 1.5 hours each morning.  If you operate 3 days a week, this is 4.5 hours x 10.00 = 45 a weekend x 52 weeks is $2340.00 per year in inflation costs.
2. On average it takes 2 employees an hour each to squeegie, clean and was the bunkers with vinyl.  With Vortex Bunkers there is very little clean up.  Referees will walk with towels in their pockets.  Any visible paint splats will self dry from the air pushing through the bunkers.  About an hour after a wet paint splat, a damp towel will clickly remove it.  This should all be done while reffing.  So at night time, referees simply pull the batteries and set up for charging.  again we will use 30 minutes.  Again the savings is 2 hours – .5 hours each day.  If you operate 3 days a week, this is 4.5 hours x 10.00 = 45 a weekend x 52 weeks is $2340.00 in take down savings a year.  
3. Vinyl bunkers require you to patch the bunker immediately when there are small leaks or rodent holes or else you will be needing a blower all day and an employee to keep them inflated.  Vortex Bunkers will stay inflated even with minor holes that need patching later.  Fabric patches are quickly applied with spray on glue and supplied fabric for patching.  On average most fields will spend 5 labor hours a month maintaining vinyl bunkers.  5 x 10 = 50.00 a month x 12 months is 600 a year.
4. Total savings in year one is $2340 + 2340 + 600 = 5280 annually.  
5. Vortex Bunkers do not need annual or semi-annual replacement.  The “skins” without repurchasing a whole new bunker are $40.00 a bunker cheaper than a complete set.  You can simply replace whatever skins needed on an as needed basis.  Gone are the days you need to shell out 5000 to 7000 for a complete set replacement.  Buy in only the skins that are worn out.
