|Comparison||GRAIN BAG||DARMANI BIN|
|Length of storage time||TEMPORARY
Recommended 4-8 months max.
As long as you want.
|Spoilage||Studies show @ $0.10/bushel .||Virtually zero with aeration.|
|Monitoring||Difficult.||EASY with temp cables.|
|Maximizing weight||Can't be done.||EASY with moisture cables and aeration to add weight increasing market value.|
|Moderate to extremely high depending on commodity and length of time stored.||Extremely low if monitored.|
|Very high in areas with wildlife such as bears, caribou, elk, deer, birds, crows.||Zero.|
|High – one rip/tear can leave grain susceptible to all sorts of unwanted critters.||Zero - bugs can be controlled with aeration and rats/mice don't' like steel floors.|
|Risk Level Theft/Vandalism||High – bags are out on farmland with usually nobody around so are susceptible to both vandalism and grain theft .||Zero - steel bins are usually on farm storage and can be locked.|
|Filling at harvest time||If rented land – can put on remote land locations eliminating some trucking times.||If owned land - Can put on home farm Note: Darmani 52" lids make it easier to fill at harvest time than most bins.|
|Unloading||Difficult - Takes extra labour.||Easy - with fast unloading augers.|
|Unloading extra labor times||
Difficult - Often time, a lot of snow removal has to be done prior to getting access to bags.
|Easier - Unloading at farm is easy snow can be controlled.|
|Ability to take sample||Hard- have to get access and then reseal - always run the risk of oxygen/moisture problems.||Easy - just draw one load.|
|Environmentally-friendly||No - have to dispose of bags. May be extra charge to do so.||Yes.|
|Equipment required||Grain bagger, unloader, grain cart.||No additional equipment as use existing augers.|
|Equipment cost||$125-175,000||No additional equipment|
|Grain bagging $0.37/bushel.

|Comparison||FULL FLOOR||DARMANI CROSS AIR|
|Static Pressure||High - Air is forced from the bottom.||Substantially reduced as air has @ 6' less to push as cross air is suspended.|
|Air Restrictions||High - Air is restricted by having to force air through small holes leaving only 17% open area.||Zero - All the air is blown out.|
|Air movement (air travels path of least resistance)||Good - Full floor is better than square pits in that it reaches outsides better having perforated material to the ends.||Excellent - Cross air is designed to have the air blow evenly on all sides of the bin.|
|Centre core air movement||Good - Full floor aeration allows air to move in all directions.||Excellent - With optional cross air tower, the air travelling through the center core and up the center is greatly increased.|
|Problem - At some point in bins life, fines/build up occurs causing air to force fines into floor filling up underneath blocking air flow. This has to be disassembled, cleaned and then reassembled.||No problems - never have to reassemble.|
|Ice/snow build up concern||Potential Problem - Center clump build up can cause centre unload gearbox to jam leaving bin unable to be centre unloaded.||No problems - As centre is covered with galvanized material, big clumps can't build up.|
|Cleanout||Good - When purchased with a center cleanout system, all customer needs is a broom.||Good - Cross air is raised so when purchased with unload system, all customer needs is a broom.|
|Bin access||Hard - Bins with full floor have panels that have to be removed prior to access.||Easy - Darmani bin features easy access door with vertical lift chute.|
|Foundation required||Full floor aeration only works with concrete.||Cross air works on both steel floor or concrete foundations.|
|36' Air material cost||$7450 (includes below)
Full floor aeration (.050 perf.).
Synitiro floor supports transition.
|$4199 (includes below)
Structural tubular framework -Rolled galvanized tubing - Bin support brackets - Fan transition
*optional center tower $945 (includes supports to attach to peak ring)

|Checking bins||Moderate to hard - Easier than regular ladders. Still have to climb a lot of stairs.||Easy - Like taking elevator at hotel.|

|Cost effective||One staircase with platform can accommodate two bins.||One skylift with platform can accomodate two bins|
|Priced on 36' Flat bottom bin costing||$4200 Includes staircase and connecting platform and labor to install if building a new bin package.||$2250- Includes one skylift and connecting platform and labor to install if building a new bin package.|

|Easy - Bin bolts on the outside of the steel floor.|
|Sizes/availability||Up to 36' diameter||Up to 36' diameter|
|Cure time||28 days.||N/A|
|Foundation requirements||Remove topsoil use gravel/clay/sand mixture pack down well.||Remove topsoil use gravel/clay/sand mixture pack down well.|
