Cleaning ventilation ducts: disinfection rules, prices


specialist cleans pipes with a brush

Res­i­den­tial build­ings, build­ings of insti­tu­tions, enter­pris­es have an indi­vid­ual ven­ti­la­tion sys­tem to ensure air exchange, con­sist­ing of shafts, air ducts and chan­nels. Domes­tic and indus­tri­al ven­ti­la­tion becomes dirty dur­ing oper­a­tion and requires peri­od­ic clean­ing.

The need to clean ventilation

why does air duct get dirtyExhaust ven­ti­la­tion ducts dur­ing oper­a­tion become con­t­a­m­i­nat­ed with par­ti­cles of dust, grease, chem­i­cal fumes of house­hold chem­i­cals. Sup­ply ven­ti­la­tion going into the room from the street becomes clogged even faster.

Enter the air duct

  • dust,
  • traf­fic fumes,
  • dry leaves,
  • insects,
  • trash.

The accu­mu­lat­ed dirt set­tles on the inner sur­face of the chan­nel, nar­row­ing the ven­ti­la­tion hole. This reduces air exchange, leads to an increased load on the ven­ti­la­tion equip­ment and reduces its ser­vice life.

If the ven­ti­la­tion ele­ments locat­ed in cold rooms are not insu­lat­ed, then con­den­sate appears and accu­mu­lates inside. An increase in humid­i­ty cre­ates a favor­able envi­ron­ment for the growth of fun­gi and mold. In areas with open areas, it is con­ve­nient to install flex­i­ble insu­lat­ed air ducts.

Duct pol­lu­tion is a haz­ard to human health and safe­ty for the fol­low­ing rea­sons:

  • Dete­ri­o­ra­tion of air qual­i­ty;
  • The appear­ance of mold, fun­gi;
  • Repro­duc­tion of path­o­gen­ic microor­gan­isms;
  • Increased fire haz­ard.

Signs of clog­ging can be the accu­mu­la­tion of dust and debris on the ven­ti­la­tion grill, the rapid dusti­ness of the room after wet clean­ing, over­heat­ing of the air, the absence of drafts when open­ing doors, and fre­quent fog­ging of win­dows.

Reg­u­lar inspec­tion and removal of con­t­a­m­i­nants is a must. In the EU, such work is reg­u­lat­ed by law. Refusal to clean ven­ti­la­tion ducts, espe­cial­ly in crowd­ed places, is fraught with the spread of infec­tious dis­eases that have an air­borne trans­mis­sion mech­a­nism.

Cleaning ventilation in an apartment or house

vacuum cleaning processVer­ti­cal ven­ti­la­tion shafts in apart­ment build­ings belong­ing to com­mon prop­er­ty are cleaned by spe­cial­ized orga­ni­za­tions. The con­tract for the work is signed by the man­age­ment com­pa­ny.

You can inde­pen­dent­ly clean the sleeve to the shaft mechan­i­cal­ly, for this you need:

  • To pro­tect against debris cov­er floor and wall under the ven­ti­la­tion grill;
  • Install lad­der or oth­er sta­ble fix­ture;
  • Put on per­son­al pro­tec­tive equip­ment (gloves, res­pi­ra­tor);
  • Remove grillunscrew the fan if present;
  • care­ful­ly them wash with a fat-sol­u­ble deter­gentwipe dry;
  • Using a flash­light, inspect the places of con­t­a­m­i­na­tion;
  • By hand or spat­u­la remove large debris;
  • With a brush, met­al brush clear fat depositsdust from the inner sur­face of the chan­nel;
  • Remain­ing dirt can be removed using a vac­u­um clean­er;
  • Install the fan, grille in place.

If plas­tic air ducts are installed for ven­ti­la­tion, then mechan­i­cal clean­ing should be car­ried out care­ful­ly to avoid dam­age to the walls.

Pro­fes­sion­al ser­vices for clean­ing ven­ti­la­tion sys­tems use sev­er­al meth­ods:

  • Mechan­i­cal using vac­u­um clean­ers and brush machines;
  • Chem­i­cal — spray­ing of spe­cial chem­i­cal solu­tions in air ducts;
  • Cryo­genic clean­ing dry ice — absolute­ly safe and effec­tive on any sur­face.

Professional ventilation cleaning

Mod­ern equip­ment for clean­ing ven­ti­la­tion ducts allows you to per­form clean­ing work in a high qual­i­ty and in a short time:

  • brush machine — removes dust deposits mechan­i­cal­ly;
  • steam gen­er­a­torsprayer, com­pres­sor — cope with fat­ty con­t­a­m­i­nants chem­i­cal­ly;
  • Core, punch. Used to clean air ducts when clog­ging with con­struc­tion waste;
  • brush­es dif­fer­ent diam­e­ters, mount­ed on a flex­i­ble shaft. Are made round, square, rec­tan­gu­lar sec­tion;
  • flex­i­ble rod — a device for clean­ing turn­ing sec­tions. Adapters at the ends of the rod allow you to attach brush­es to it;
  • Pow­er­ful roomy a vac­u­um clean­er;
  • Met­al ruffs.

Pro­fes­sion­al clean­ing of ven­ti­la­tion ducts takes place in sev­er­al stages:

  • Diag­no­sis of the state of ven­ti­la­tion shafts and cham­bers is car­ried out using video inspec­tion sys­tems;
  • Removal of block­ages;
  • Sam­pling for total micro­bial count in sed­i­ment washouts and air sup­ply;
  • Clean­ing from dust, grease and oth­er con­t­a­m­i­nants;
  • Car­ry­ing out dis­in­fec­tion.

After the work car­ried out, an act of admis­sion to oper­a­tion and a plan for peri­od­ic inspec­tion are drawn up.

Cleaning ventilation from grease in a restaurant

Cater­ing estab­lish­ments are oblig­ed to car­ry out pro­fes­sion­al clean­ing of ven­ti­la­tion sys­tems on a reg­u­lar basis.grease on duct walls

  • Huge amount of fatformed dur­ing cook­ing, and ele­vat­ed tem­per­a­tures con­tribute to rapid con­t­a­m­i­na­tion.
  • Fat, cool­ing on the inner sur­face of the chan­nels, forms a hard-to-remove lay­er.
  • He cre­ates a favor­able envi­ron­ment for the repro­duc­tion of path­o­gen­ic microor­gan­isms and bac­te­ria, which is unac­cept­able in restau­rants.

Clean­ing of ven­ti­la­tion ducts from grease is car­ried out by a chem­i­cal method.

  • An alka­line solu­tion is applied to the walls of the chan­nels with a spray gun and washed off under pres­sure.
  • Thick lay­ers of fat­ty accu­mu­la­tions are cleaned with met­al brush­es.

With inten­sive work of the hot shop, clean­ing should be done once a month. To reduce con­t­a­m­i­na­tion, grease traps are installed.

Accord­ing to Fed­er­al Law No. 52 of March 30, 1999 “On the san­i­tary and epi­demi­o­log­i­cal wel­fare of the pop­u­la­tion”, when prepar­ing, stor­ing and sell­ing food and drinks, san­i­tary rules must be fol­lowed to pre­vent the occur­rence and spread of infec­tious dis­eases and mass non-com­mu­ni­ca­ble dis­eases.

Clean­ing and dis­in­fec­tion of air duct sys­tems refers to san­i­tary and pre­ven­tive mea­sures that are manda­to­ry and con­trolled by the state san­i­tary and epi­demi­o­log­i­cal super­vi­sion.

Sched­uled hygiene checks should be car­ried out at least once every 6 months.

After receiv­ing the results of micro­bi­o­log­i­cal tests, a deci­sion is made on the need for dis­in­fec­tion.

Car ventilation duct cleaning

machine processingThe car ven­ti­la­tion sys­tem also needs peri­od­ic clean­ing. The rea­son may be the appear­ance of an unpleas­ant smell in the car.

Inde­pen­dent per­for­mance of work is car­ried out with the help of spe­cial aerosols. For this you need:

  • Free the salon from unnec­es­sary things and objects, an aerosol is a chem­i­cal agent;
  • Remove cab­in air fil­ter;
  • Start the engineturn on the air con­di­tion­er in low tem­per­a­ture mode, close the doors for 5 min­utes;
  • After the time has elapsed, install a cylin­der on the floor near the front pas­sen­ger seat, turn on the air­flow, press the spray but­ton and close the door;
  • The aerosol will begin to recir­cu­late along with the air in the vehi­cle’s ven­ti­la­tion sys­tem;
  • Open doors after 15 min­utes for ven­ti­la­tion;
  • After turn­ing off the blow­er, air con­di­tion­ing, turn off the engine;
  • Replace the cab­in fil­ter with a new one.

Self-clean­ing car ven­ti­la­tion ducts is not a dif­fi­cult and eco­nom­i­cal option. The min­i­mum cost of aerosol clean­ers is from 5 dol­lars.

You can go to a ser­vice sta­tion for pro­fes­sion­al clean­ing. This is a reli­able option, besides with a war­ran­ty. The min­i­mum price of ser­vices is from 36$.

Ventilation disinfection

Dur­ing the clean­ing process, sam­ples of con­t­a­m­i­nants are tak­en for lab­o­ra­to­ry analy­sis.

If the per­mis­si­ble val­ues ​​of micro­bi­o­log­i­cal indi­ca­tors are exceed­ed, dis­in­fec­tion is car­ried out -

  • destruc­tion of path­o­gen­ic microor­gan­isms,
  • bac­te­ria inside chan­nels and air ducts.

It is per­formed only after clean­ing. This is an impor­tant event for main­tain­ing a favor­able micro­cli­mate in the premis­es, ensur­ing the health and well-being of a per­son.

To do this, the cleaned sur­faces of the chan­nels are treat­ed with a dis­in­fec­tant solu­tion approved by the State San­i­tary and Epi­demi­o­log­i­cal Super­vi­sion.

After dis­in­fec­tion, new sam­ples are tak­en from the canal walls to con­firm the effec­tive­ness of the work done.

Dear Heads of indus­tri­al and food enter­pris­es, insti­tu­tions, man­age­ment com­pa­nies and home­own­ers asso­ci­a­tions, take mea­sures to ensure our gen­er­al san­i­tary safe­ty — plan, car­ry out and con­trol the clean­ing and dis­in­fec­tion of ven­ti­la­tion sys­tems.

Ventilation cleaning equipment

Depend­ing on the size and mate­r­i­al of man­u­fac­ture of ven­ti­la­tion shafts, air ducts, as well as the degree of their con­t­a­m­i­na­tion, the equip­ment nec­es­sary in terms of pow­er and con­fig­u­ra­tion is select­ed.

The tech­nol­o­gy for clean­ing inflex­i­ble and flex­i­ble ducts for ven­ti­la­tion is dif­fer­ent. Overview of aver­age prices:

  • A set of 5 brush­es for mechan­i­cal clean­ing will cost 90 dol­lars;
  • Flex­i­ble 6 meter shaft for their attach­ment — 120$;
  • Met­al ruffs from 2,5 dol­lars;
  • Brush machine — 1050$;
  • Vac­u­um clean­er with a flex­i­ble shaft — 750$;
  • A set of steam gen­er­a­tor and atom­iz­er with an addi­tion­al set of tools for remov­ing grease — 1500$;
  • Video inspec­tion sys­tem from 450$.

How much does cleaning and disinfection cost?

system cleaning in a catering establishmentIt is advis­able to car­ry out self-clean­ing only in rela­tion to prop­er­ty relat­ed to pri­vate prop­er­ty (for exam­ple, a hose to a com­mon shaft in a city apart­ment, usu­al­ly its length does not exceed 0.5 meters).

To do this, it is enough to pur­chase per­son­al pro­tec­tive equip­ment, a met­al brush and a grease remover.

It is for­bid­den to clean the com­mon house mines on your own. It is impos­si­ble and very dan­ger­ous to car­ry out dis­in­fec­tion on your own.

The cost of ser­vices of spe­cial­ized ser­vices for clean­ing and dis­in­fec­tion of air ducts depends on the com­plex­i­ty of the work per­formed.

Prices are influ­enced by fac­tors such as

  • avail­abil­i­ty of chan­nel loca­tions,
  • degree and nature of pol­lu­tion.

The basic cost of work is usu­al­ly cal­cu­lat­ed per 1 square meter of air duct, clean­ing ven­ti­la­tion ducts price:

  • Video diag­nos­tics from 50 dol­lars;
  • Mechan­i­cal clean­ing of dust deposits from 170 rubles;
  • Clean­ing of fat­ty deposits from 7,5 dol­lars;
  • Micro­bi­o­log­i­cal sam­ples — 1,5 dol­larsper flush;
  • Dis­in­fec­tion from 50 rubles.

Clean­ing of ven­ti­la­tion ducts is a nec­es­sary manda­to­ry mea­sure reg­u­lat­ed by the Leg­is­la­tion of the EU and aimed at ensur­ing the health and high work­ing capac­i­ty of the pop­u­la­tion.
