APPLICATION:

The filter canister in connection with a suitable respirator or PAPR provides protection against solid and liquid particles, pepper spray (OC), smoke-producing substances, radioactive particles, bacteria and rickettsia, fungi, toxins, viruses, riot control agents (lachrymators, sternutators, vomiting agents), blister agents (vesicants), choking agents, blood agents, nerve agents, incapacitants, herbicides, pesticides, and TIC, such as bromoacetone, CS, CR, CN, CNC, CNS, CA substances, organic compounds of arsenic - diphenyldichlorarsine - CLARK I (DA), diphenylcyanoarsine - CLARK II (DC), adamsite (DM), diphenyldichlorarsine (DA), ethyldichlorarsine (ED), methyldichlorarsine (MD), mustard gas (H), sulphur mustard gas (HD), T-mustard gas, Q-mustard gas, nitrogen mustard gases (HN1, HN2, HN3), lewisite (L), mixed mustard gas (H-L), phosgene oxime (CX), phosgene (CG), diphosgene(DP), chloropicrin (PS), hydrogen cyanide (AC), cyanogen chloride (CK), arsine (SA), G-agents: sarin (GB), cyclosarin (GF), soman (GD), tabun (GA), IVA (GV), V-agents: VX, VR, VE, VG (amiton), VM and toxic industrial chemicals such as: fumes of organic or inorganic acids, hydroxides, organic solvents with a boiling point above 65° C, ammonia, amines, inorganic and acid gases, agricultural chemical combustion gases, other toxic substances, e.g. benzene, toluene, vinyl chloride, fluorine, hydrogen fluoride, sulphur oxides, chloroacetic acid, aldehydes, mixtures of inorganic acids, and organic substances, mercury vapors, radioactive iodine, organic compounds of iodine (Iodomethane, 129, 131), radioactive particles, etc.

LIFETIME:

Breakthrough time of a filter is tested according to EN 14387+A1 at humidity 70% and flow rate 30 l/min, which is equivalent to the volume of air per minute used by an average person carrying out medium heavy work. The approximate lifetime (usage time) of a filter may, under normal conditions, calculated by comparing the concentration at the workplace and the minimum Dynamic Adsorption Capacity (DAC) for the filter.


STORAGE AND MAINTENANCE:

The filters are sealed in plastic bags by the manufacturer. Store the filters unopened in a clean place at even temperature, most appropriate at -5 to +30°C and relative humidity below 80%. Sealed filters tolerate also conditions of -30 to +50°C and RH below 95%. The storage period (month and year) for filters is marked on the filter label. Do not try to regenerate the filters. Never clean the filters with compressed air or compressed water.


DISPOSAL:

After use, the filters are special refuse. Make sure that they are disposed of according to the filtered substance (gases or particles) in accordance with current waste treatment regulations. If the product is to be disposed of, it should be dismantled from the respirator and disposed of as solid waste. Please see local authority regulations for disposal advice and locations.

Solid unit, not showy 9thank you)
Style: R-S202BL, Configuration: w/o Wire and Plug
FAST!! shipping, complete, well packaged, excellent price for Yamaha durability. Easy hook-up, normal sized manual (thanks again!). Smile, intuitive controls. Base and treble by front-panel pots. I would have paid extra for a lighted remote.

This item was sold at a NEW price and it was CLEARLY USED.
Style: R-S202BL, Configuration: w/o Wire and Plug
Unfortunately I really didn’t get to operate this item due to the fact that it didn’t work. After I connected my speakers and plugged it in, I turned on the power switch and the lights came on, but no sound. No discredit to Yamaha, nor the item... this is on the seller. It was sold at a new price and it was clearly a used item. Upon opening the box, I noticed : 1. The power cord was wrapped with a dirty, pink hair band. 2. The unit was not in plastic like a new item. 3. The FM antenna was missing. 4. The remote had old, used batteries in it. This should not have been re-sold.

a cult that still goes on...
Style: R-S202BL, Configuration: w/o Wire and Plug
Update in 2023: I have to add that I made this ppurchase via Amazon and it arrived at me in mint condition (Amazon Renewed scheme with 90 days money back guaranteed). For hifi components, if it works for the first quarter, it will then work rest of years. Mine though opened box but mint in sense that both its cosmetics and functions work perfectly. I purchased beefier models of Yamaha same series, the As 301r and As 501r afterwards via Amazon. Other than delicacy, the AR 202 receiver's overall performance is comparable to its leveled up siblings... AR 202 has already become a legend in hifi history since 2018... Yet of course audiophile ears are more picky and won't stay still with this kit. Therefore I purchased the silvery stereo amps afterwards cux I knew prices would go up very high and it is now proven positively and more so... Grab one even if used as ye still may... The AR 202 has an extraordinarily energetic drive in stereo sound given it's the youngest brother in the family. It brought much glory to the whole brand indeed... Review in 2019: "...performs much better than the beefed up version 100v Yamaha A-S301 silver in way of responsive and agile bass, larger soundstage, impressive midrange and fine treble. no wonder it is the best selling amp in 2017 and 2018. i suppose the cult still goes on......"

Well made, a solid connection.
Size: 6 Pairs / 12 pcs
I liked them. They really lock down on the speaker wire to make a firm connection. They seem well made and are easy to install. My system sounds great.
