Flyboy Yes. Most adults can wear these mask quite well. These are N95 Surgical Mask, used in operating rooms in many countries, by medical professionals around the world. They are comfortable, and will 'adjust' to most all adult faces. Please be aware, if a person has a narrow, or longish face, it may be necessary to 'knot' the ear bands in order to shorten them for a comfortable fit. These mask were originally designed and manufactured assuming one time use. They can be used a number of times, and sanitized after several uses, with an ultra violet light (sic, black light). A black light bulb is available at larger department stores, hardware stores and home improvement centers, for approximately $3.00 to $4.00 (U.S. $'s). It is a standard base bulb, usually 60 watts that can be used in any lamp. Position the masks around the bulb (no shade), about 1 foot distance (30 cm), for a minimum of 2 hours, to maximum 4 hours, be sure to 'sanitize' the outside of the mask first (up to 4 hours), then the inside for 2 hours. Washing, or spraying with disinfectant chemicals will deteriorate the mask quickly. BTW, 10 N95 Surgical Mask for $18.00 (U.S. $'s) is a bargain! In March/2020, I ordered 10 paid, $42.00 (U.S. $'s) with shipping! Hope this helps!

Q: Is it a police scanner

Задавает BG142217161 на 2020-11-05 07:19:50

Flyboy No. This is not a police or general scanner. This is a FM walkie-talkie. The range is great, 1 to 3 miles (1.6 to 3.8 KM), depending on local RF interference. The Walkie-Talkie has FM frequency (sic, channel) scanning, i.e.; if one channel becomes 'busy' the walkie-talkie will scan, find a clear frequency, then set to send & receive on the new frequency, all automatically, seamlessly to the user. It is a great walkie-talkie for a moderate price.

Q: Who is the supplier of masks ? Are they CE certifiée?

Задавает BG455351710 на 2020-04-13 09:30:27

Flyboy Thank you for your questions and the opportunity they present to serve you. Your question #1: "Who is the supplier of masks?" - In this case, the supplier is Banggood, from whom you are ordering.From the general nature of your question, I assume you meant; who is the manufacturer of the mask? Yes? If so, the manufacturer is a large Chinese manufacturing Company, Yi Miao An. Your question #2; "Are they CE certifiée?" That information is privy only to the manufacturing company, Yi Miao An Manufacturing will have to answer that question for you. Please feel free to contact them directly. From the general nature of your question, I assume you may have meant; Are the mask CE certified? Yes? If so, the mask are certified by the following international ratings: Kn95, N95, FFP2, KF94 and K8600. These ratings are listed both on the mask, or in the description.You can check with CE Headquarters in your country to find out which of these international standards they use.

Flyboy The real answer to your question about delivery in a certain number of day, primarily lies with the Customs of your country, how fast your Customs processes shipments through. Good luck and a speedy delivery!

Flyboy Too late to expedite. Shipped, is shipped. The time to expedite the shipping is during the ordering process at check out. Simply choose a faster shipping method.From the sound of things, your order is probably held up in U.S. Customs, and unfortunately may be for a while. U.S. Customs is not exactly 'hurrying' Chinese shipments through Customs lately. That's the good news. On the down side, if Customs opens the shipment for inspection, which they have every right to do, it's their job. Once discovered, the Customs officials may well confiscate the masks, for use in military hospitals, clinics, etc. Good luck and hopefully your masks will sneak their way through Customs and into your mail box soonest.

Q: reuse

Задавает Kottkawa на 2020-04-03 05:25:35

Flyboy Yes. Can reuse, after disinfecting. Use UV Light to disinfect, minimum time, 2 hours, 4 hours is best. Do not use any liquid to disinfect, i.e.; alcohol, chlorine bleach, disinfectant spray, etc., the liquid will cause the filter media to disintegrate. Mask will then be useless.

Flyboy Hola, La velocidad del viento en tu región es de 5,28 ms, la velocidad nominal del viento para una producción máxima de 13 ms. Esta velocidad del viento producirá energía, pero no la máxima. Asegúrese de comprar el molino de viento con cinco palas para su área. Este molino de viento funcionará para ti. ¡Buena suerte! Ray

Q: la produccion es de 1200 w por hora o por dia ?

Задавает claudionsanchez на 2019-08-17 12:42:42

Flyboy Hola, The output of a windmill generator is dependent on the wind speed, therefore the output varies depending on the wind speed, which also varies. The output 1200 watt rating of this generator is at the 'rated wind speed' of 13 ms (29 mph). At slower wind speeds the output will be less and at higher wind speeds the output may be slightly more, but there are several dynamic factors that effect windmills, especially at higher wind speeds. I hope this helps!

Flyboy Your option 3) is your best configuration.It would be most efficient to setup the system with remote switching (simple on/off switches and relays to switch the incoming charging flow into the battery bank) and for example; a) use solar cells input for charging during the day, b) use windmill output for charging at night, c) other times, use the charging source that will give the most charging output, winter storm, heavy clouds, lot of wind, use the windmill charging day and night.

Q: what is the rotor rpm?

Задавает nsvsreddy на 2019-10-04 08:36:07

Flyboy Interesting question! The rotor rpm is directly dependent on the wind speed. See, this is a WINDmill. OK? No wind, no rotor rpm. wind at 13 m/s (29 mph), will result in maximum power output from the generator, 1200 watts, at whatever rpm that may be. What is the rotor rpm, unknown! The manufacturer does not supply that information. (durn!) Additionally, there is a gear drive between the propeller head and the generator armature, so, there are two (2) different 'rotors' involved, the propeller and the generator armature. Which 'rotor' are you asking about? And, does the rpm of either 'rotor' actually matter? So long as; at the prescribed wind speed (13 m/s, 29 mph) the generator outputs 1200 watts.

Q: what is it's rpm(rotations per minute of the generator) but not the wind speed.

Задавает nsvsreddy на 2019-10-06 06:10:36

Flyboy This information is not supplied by the equipment manufacturer. The actual rpm of the generator armature is totally dependent upon the wind speed at any given moment. Secondly, there is a gear drive between the propeller head and the generator armature, consequently the rpm of the generator armature is dependent upon two (2) factors; a) wind speed at any given moment, b) the gear drive ratio.

Q: Does it need a dump load device?

Задавает arthurmyburgh на 2019-06-26 03:38:44

Flyboy No. The windmill generator comes with a charge controller. What is needed to make a full working installation: a) tower, or mast to mount the windmill on, b) battery, or batteries to connect to the charge controller, c) inverter to connect to the battery, or batteries to convert the dc voltage to ac voltage for use, d) connecting cables from the charge controller to the battery or batteries, e) a suitable enclosure for the charge controller, battery, or batteries and inverter.
