Checked out the compressor. The pressure switch wasn't the problem, but at least it's adjusted now. And the PRV tested 😤

Looks like the motor capacitor is getting lazy. Not unusual, but a bit annoying given that this thing is maybe a year old and not used heavily.

Perhaps they used the wrong element. SeaKnight instead of AirKnight :blobcatdizzy:

Close-up of a black plastic box with red knob on top, which houses a pressure switch for switching the compressor on when the air pressure drops below a threshold, and off again when it reaches another one that should be around 8 bar. There's also a red regulator knob and two gauges. On the right is a standard air hose coupling, on the left a red plastic cover for the pump.
Close-up of a large white motor run capacitor popped out of its black housing underneath the compressor pump. The cables are still attached. The label reads SeaKnight CBB60 30μF 450V.

Paris Bike Boom Leads to Steep Drop in Air Pollution

"The French city’s air quality has improved dramatically in the past 20 years, coinciding with a growth in cycling...Between 2005 and 2024, levels of nitrogen dioxide and fine particulate matter — two of the most harmful pollutants to human health — have been slashed by 50% and 55%, respectively.”

"City leaders including Mayor Anne Hidalgo have been making a concerted effort to pedestrianize parts of the city, improve bike infrastructure, and promote active transportation in the French capital."

Dear Friends,
These two trees, a beech on the left, a walnut on the right have been objects of admiration for some time.

Yesterday, the sky was this gray.

Recalling this moment -
the cool air moving above and around,
through my nose, into my lungs, then back out
head upward - breathe, click, breathe.

Stating the obvious - all of this is a miracle.

The branches of a Beech tree with early signs of flowering and the still bare branches of walnut tree are silhouetted against a cloudy, solidly gray sky.

All sorts of #toxic materials are released into the #atmosphere when buildings and their contents #burn. It's why one sees urban #firefighters donning breathing apparatus. #Wildlands adjacent to the Los Angeles basin also contain #mercury and #lead in #soil and litter layers, deposited over many years from #air #pollution generated by vehicles and industries. #Wildfires often emit these heavy metals.
