(1) Full power or not?  Natural’s heaters are Full Power, for this, it is very easy to check, you just connect with the heaters with city power, then after 40 minutes later, when the power stable, then check the power display, you will see the true power for it. Natural are offering full power, but right now, market has half power, for example, on sticker write 100W, in fact, only have 50W, so on sticker is fake power.

(2) Plastic material for heater, Natural adapt new PA66 UL 94 V-0, some company adapt used material, for this, it is very easy, you just use fire to fire it, then smell, if it is smelly, this means the material is used material, another, to check the color of the products, used material color is dark and sometimes with black point on the products.

(3) Natural’s Heater adapt Shell fully oxidized, some company adapt half Shell fully oxidized, which will oxidize after some time.

(4) Natural’s heater is 100% high-pot testing by 1600V 3 seconds(UL requirement is 1200V 3 seconds), and function testing.  Each pc need to test.  For example, if you order 2000pcs, then we will test 2000times by hi-pot testing and 2000 times of function testing.  

(5) Another, for the terminal connector, we adapt is UL listed terminal connector, not normal type.

(1) Natural’s LED lamp adapt pure PC material, which is clear color, never adapt used material.

(2) Natural’s LED Lamp will not fall down from top of the cabinet or enclosures, for this, you also can test by hanging heavy things, we hanging one 1.5KG thing onto our LED Lamp, it will not fall down, so you can check others, if them can carry this weight to the top of the cabinets and enclosures? If you not know how to test it, we can send you the video to show.

(3) Natural’s LED Lamp voltage is 48V-265VAC/DC, both can use for AC and DC system. With big voltage range. Another, we also have 24VDC type, Natural’s LED 025 can connect one by one by 5pcs same time, also can Individual control, which means, you can make off anyone of the 5pcs, other 4 lights will still be on.  

(1) Natural’s Filter Fans all adapt new UL listed materials. Never adapt used material, some company adapt used material, for this, it is very easy, you just use fire to fire it, then smell, if it is smelly, this means the material is used material, another, to check the color of the products, used material color is dark and sometimes with black point on the products. For the ones that adapt used material, after some time, when you press the cover of the filter, it will break, for ours, not break. Because used material feature is not so stable as new material, will get aging fastly.

(2) Natural’s Filter not add CACO3 material into product, CACO3 will make the material harder than normal, but it will reduce the using life of the filter fans, get aging fastly, Natural’s filter fans not add this kind of material, so will have longer using life.

(3) Natural Filter Fans inside adapt copper wire, not adapt aluminum wire or painting copper wire, Natural’s copper wire diameter is 1.1mm, not 0.8mm. Maybe you will ask how to check if the wire is copper or aluminum? Fire it, if the fired place easy to fall down, means the wire is aluminum, if not fall down, just bend, which means is copper.

(4) Natural’s fans have 32 floor Silicon steel sheet, not 28 floor or 26 floor, for this, you can open the fans and check inside the floor of the Silicon steel sheet, you will know the difference.
