THE RUDOLF REPORT

5. AUSCHWITZ5.4.1.2.4. Ventilation InstallationsFact: All rooms in crematoria II and III were equipped with efficientventilation installations. 216Incorrect conclusion: Morgues 1 of crematoria II and III wereconverted into homicidal ‘gas chambers’ equipped with installationsfor the intended purpose of evacuating poison gases. 217Correct conclusion: It is in fact inconceivable that a large morguewithout windows and with only one door filled with innumerable bodiesof the victims of epidemic disease would not be equipped with aventilation installation. The efficiency of the ventilation, however,proves that these installations were designed for typical morgues. 218The efficiency of the blowers may be seen from the invoices sent to theZentralbauleitung by the Topf corporation after installation of the systems.219 According to the invoices, both morgues #1, i.e., the alleged‘gas chambers’ (in the invoice designated as the “B-room”), were eachequipped with a 4,800 m 3 /h intake and outlet blower, 220 while for the“L-room” (the so-called “undressing room”) only one outlet blowerwas installed, with a capacity of 10,000 m 3 /h. 221216 The ventilation ducts of morgue 1 are visible in the plans published by J.-C. Pressac, op. cit.(note 67), pp. 224, 289; chapter on the ventilation installations of crematoria II and III: ibid.,pp. 355ff.; engine power of the ventilation installations for all rooms in crematoria II and III:ibid., p. 374 and 377; size of the ventilation outlets: ibid., p. 234; Fig. of an outlet cover in theventilation outlets.217 For Pressac see footnote above; a similar opinion has been expressed by Van Pelt, Pelt Report,op. cit. (note 66), p. 208, as well as by Judge Gray in the Irving vs. Lipstadt trial, op. cit. (note66), §7.62.218 See also, in this regard, Carlo Mattogno, “Auschwitz. das Ende einer Legende”, in: HerbertVerbeke (ed.), op. cit. (note 43, also the English version), pp. 134f. (online: Ger.:www.vho.org/D/anf/Mattogno.html; Engl.: www.vho.org/GB/Books/anf/Mattogno.html). Thefollowing remarks are closely patterned after Mattogno; for further details, see Mattogno.219 Invoice no. 729 dated May 27, 1943. APMO, D-Z/Bau, nr. inw. 1967, pp. 246f.; ibid., 231f.:invoice no. 171 dated 22. February 1943 for crematorium II.220 The engines had a nominal output of 2 HP (approximately 1.5 KW). The output data relate toa back-pressure of 40 mm water column. The increment calculations for estimating the ventilationshaft resistances in crematoria II & III according to engineering handbooks have shownthat the back pressure to be expected would probably have been higher (in the region of 50-60mm water columns), due, particularly, to the primitive lids with many small holes covering theventilation slit. Two blowers were probably used for this reason. Personal communicationfrom Hans Lamker, a certified engineer.221 J.-C. Pressac gives the output of these blowers at 8,000 m³/h, but without proving it (togetherwith Robert van Pelt in: Yisrael Gutman, Michael Berenbaum (ed.), Anatomy of the AuschwitzDeath Camp, Indiana University Press, Bloomington 1994, pp. 210, 232). Perhaps he simplycrudely added the output of the two blowers together, which is impermissible, since the blowersdid not work in parallel, but rather, in series (behind each other).107
